Despite successes, these standards support the exchange of product data more than they do process data, especially those processes that are loosely coupled with product models. This paper reports on on-going research to evaluate the adequacy of the IFC and CIS/2 standards to support process modeling in the steel supply chain. Some initial recommendations are made regarding enhancements to the data standards to better support processes.},

The main advantages are the arrangement of the tasks of a project in a clear, easily readable form and the calculation of valuable information like critical paths. The main disadvantage on the other hand is the inflexibility of the model caused by the modeling paradigms. Small changes of the modeled information strongly influence the whole model and lead to the need to change many more details in the plan. In this article an approach is introduced allowing the creation of more flexible schedules. It aims towards a more robust model that lowers the need to change more than a few information while being able to calculate the important propositions of the known models and leading to further valuable conclusions.},

Even with the increasing integration of model-based systems with project information spaces, a large percentage of the information exchange will further on rely on isolated and rather poorly structured text documents. In this paper we propose an approach enabling the use of product model data as a primary source of engineering knowledge to support information externalisation from relevant construction documents, to provide for domain-specific information retrieval, and to help in re-organising and re-contextualising documents in accordance to the user's discipline-specific tasks and information needs. Suggested is a retrieval and mining framework combining methods for analysing text documents, filtering product models and reasoning on Bayesian networks to explicitly represent the content of text repositories in personalisable semantic content networks. We describe the proposed basic network that can be realised on short-term using minimal product model information as well as various extensions towards a full-fledged added value integration of document-based and model-based information.},

  abstract  = {Iso-parametric finite elements with linear shape functions show in general a too stiff element behavior, called locking. By the investigation of structural parts under bending loading the so-called shear locking appears, because these elements can not reproduce pure bending modes. Many studies dealt with the locking problem and a number of methods to avoid the undesirable effects have been developed. Two well known methods are the >Assumed Natural Strain< (ANS) method and the >Enhanced Assumed Strain< (EAS) method. In this study the EAS method is applied to a four-node plane element with four EAS-parameters. The paper will describe the well-known linear formulation, its extension to nonlinear materials and the modeling of material uncertainties with random fields. For nonlinear material behavior the EAS parameters can not be determined directly. Here the problem is solved by using an internal iteration at the element level, which is much more efficient and stable than the determination via a global iteration. To verify the deterministic element behavior the results of common test examples are presented for linear and nonlinear materials. The modeling of material uncertainties is done by point-discretized random fields. To show the applicability of the element for stochastic finite element calculations Latin Hypercube Sampling was applied to investigate the stochastic hardening behavior of a cantilever beam with nonlinear material. The enhanced linear element can be applied as an alternative to higher-order finite elements where more nodes are necessary. The presented element formulation can be used in a similar manner to improve stochastic linear solid elements.},

Given the nature of architectural constraints, user-model interactivity is devised as the most suitable computer methodology for driving the structural synthesis process. Taking advantage of the hierarchical organization of the structural system, this research proposes a top-down approach for structural synthesis. Through hierarchical refinement, the approach lends itself to the synthesis of global and local structural solutions. The components required for implementing the proposed methodology are briefly described. The main components have been incorporated in a proof-of-concept prototype that is being tested and validated with actual buildings.},

The latter represents an established system theoretical model reduction technique which is here combined with a novel substructure technique.

In the beginning, a Finite-Rotation shell theory allowing constant shear deformations across the shell thickness is given in an isoparametric formulation. The assumed-strain concept enables the derivation of a locking-free finite element. The Layered Approach will be applied to ensure a sufficiently precise prediction of the propagation of plastic zones even throughout the shell thickness. The Riks-Wempner-Wessels global iteration scheme will be enhanced by a Line-Search procedure to ensure the tracing of nonlinear deformation paths with rather great load steps even in the post-peak range. The elastic-plastic material model includes isotropic hardening. A new Operator-Split return algorithm ensures considerably exact solution of the initial-value problem even for greater load steps. The combination with consistently linearized constitutive equations ensures quadratic convergence in a close neighbourhood to the exact solution. Finally, several examples will demonstrate accuracy and numerical efficiency of the developed algorithm.},

An adaptation of the Projective Input Residual Method to subsystem damage identification is presented. For this purpose the projected residuals were adapted with respect to a given subsystem to be analysed. Based on the gradients of these projected subsystem residuals a damage indicator was introduced which is sensitive to parameter changes and structural damages in this subsystem. Since the computations are done w.r.t. the smaller dimension of a subsystem this indicator shows a computational performance gain compared to the non-subsystem approach. This gain in efficiency makes the indicator applicable in online-monitoring and online-damage-diagnosis where continuous and fast data processing is required. The presented application of the indicator to a gantry robot could illustrate the ability of the indicator to indicate and locate real damage of a complex structure. Since in civil engineering applications the system input is often unknown, further investigations will focus on the output-only case since the generalization of the presented methods to this case will broaden its application spectrum.},

  abstract  = {In many engineering applications two or more different interacting systems require the numer-ical solution of so-called multifield problems. In civil engineering the interaction of fluid and structures plays an important role, i.e. for fabric tensile structures of light and flexible materials often used for large roof systems, capacious umbrellas or canopies. Whereas powerful numerical simulation techniques have been established in structural engineering as well as in fluid mechan-ics, only relatively few approaches to simulate the interaction of fluids with civil engineering constructions have been presented. To determine the wind loads on complex structures, it is still state-of-the-art to apply semi-empirical, strongly simplifying methods or to perform expensive ex-periments in wind tunnels. In this paper an approach of a coupled fluid-structure simulation will be presented for membrane and thin shell structures. The interaction is described by the struc-tural deformation as response to wind forces, resulting in a modification of the fluid flow domain. Besides a realistic determination of the wind loads, information on the structural stability can be obtained. The so-called partitioned solution is based on an iterative frame algorithm, integrating different codes for Computational Fluid Dynamics (CFD) and for Computational Structural Dy-namics (CSD) in an explicit or an implicit time-stepping procedure. All data exchange between the two different applications is performed via a neutral geometric model provided by a coupling interface. A conservative interpolation method is used for the interpolation of the nodal loads. The time-dependent motion of the structure requires a dynamic modification of the different grids and a redefinition of the Navier-Stokes equations in an Arbitrary Langrangian Eulerian (ALE) formulation. As an example for the present implementation, results of a coupled fluid-structure simulation for a textile membrane canopy will be presented.},

These changes are often caused by local reduction of the stiffness of the structure caused by the irregularities in the structure, as for example cracks. In simple structures such analysis can be performed directly, by solving equations of motion, but for more complex structures a different approach, usually numerical, must be applied. The problem of crack implementation into the structure behaviour has been studied by many authors who have usually modelled the crack as a massless rotational spring of suitable stiffness placed at the beam at the location where the crack occurs. Recently, the numerical procedure for the computation of the stiffness matrix for a beam element with a single transverse crack has been replaced with the element stiffness matrix written in fully symbolic form. A detailed comparison of the results obtained by using 200 2D finite elements with those obtained with a single cracked beam element has confirmed the usefulness of such element.},

  abstract  = {As computer programs become ever more complex, software development has shifted from focusing on programming towards focusing on integration. This paper describes a simulation access language (SimAL) that can be used to access and compose software applications over the Internet. Specifically, the framework is developed for the integration of tools for project management applications. The infrastructure allows users to specify and to use existing heterogeneous tools (e.g., Microsoft Project, Microsoft Excel, Primavera Project Planner, and AutoCAD) for simulation of project scenarios. This paper describes the components of the SimAL language and the implementation efforts required in the development of the SimAL framework. An illustration example bringing on-line weather forecasting service for project scheduling and management applications is provided to demonstrate the use of the simulation language and the infrastructure framework.},

  abstract  = {This paper is concerned with the numerical treatment of quasilinear elliptic partial differential equations. In order to solve the given equation we propose to use a Galerkin approach, but, in contrast to conventional finite element discretizations, we work with trial spaces that, not only exhibit the usual approximation and good localization properties, but, in addition, lead to expansions of any element in the underlying Hilbert spaces in terms in multiscale or wavelet bases with certain stability properties. Specifically, we select as trial spaces a nested sequence of spaces from an appropriate biorthogonal multiscale analysis. This gives rise to a nonlinear discretized system. To overcome the problems of nonlinearity, we make use of the machinery of interpolating wavelets to obtain knot oriented quadrature rules. Finally, Newton's method is applied to approximate the solution in the given ansatz space. The results of some numerical experiments with different biorthogonal systems, confirming the applicability of our scheme, are presented.},

  abstract  = {The AEC industry is conscious of the potentials arising from the usage of mobile computer systems to increase productivity by streamlining their business processes. Discussions are no longer on whether or not to use a mobile computer solution, but rather, on how it should be used. However, the implantation process of this new technology in Architecture, Engineering and Construction (AEC) and Facility Management (FM) practise is very slow and should be improved. One way to encourage and ease the usage of mobile computer systems in AEC is a more process-oriented usability and context appropriateness of mobile computer solutions. Context-sensitivity is defined as a crucial feature to be taken into account for further research in the area of Mobile Computing. Context-sensitive, mobile IT-solutions depend on two features: (1) flexible definitions of (construction) processes describing the context and (2) tools for flexible, multi-dimensional information management representing the context. It is on this premise that the authors propose the n-dimensional data management approach for the implementation of mobile computing solutions. In this paper, we analyse working scenarios in the AEC and FM sector, defining context aspects which are transformed and formalized as dimension hierarchies of the envisaged context model.},

Ziel des gemeinsam mit dem Institut f{\"u}r Numerische Methoden und Informatik im Bauwesen an der TU Darmstadt durchgef{\"u}hrten Forschungsprojekts ist die Entwicklung einer netzwerkbasierten Kooperationsplattform zur Unterst{\"u}tzung von geotechnischen Ingenieurplanungen.

Der Beitrag stellt die Abstraktion von Prozessmustern im Bauplanungsprozess als Basis f{\"u}r die dynamische Prozessmodellierung in einem Kooperationsmodell dar. Ziel ist es, durch die Identifikation der mit dem Entwurf und der Dimensionierung eines Bauteils verbundenen Planungs- und Abstimmungsprozesse einen bauteilbezogenen Katalog von Prozessmustern zu abstrahieren.

It presents the experience of two high-performance typical but extreme AEC teamwork cases adopting and adapting to collaboration technologies and how these technologies in practice impact their work processes. The findings illustrate the importance of collaboration technologies in cross-disciplinary, global teamwork. Observations indicate that high performance teams that use the collaboration technologies effectively exhibit collaboration readiness at an early stage and manage to define a "third way" to meet the demands of the cross-disciplinary, multi cultural and geographically distributed AEC workspace. The observations and implications represent the blueprint for yearly innovations and improvements to the design of the AEC Global Teamwork program.},

  abstract  = {The conceptual structure of an application that can support the structural analysis task in a distributed collaboratory is described in (van Rooyen and Olivier 2004). The application described there has a standalone component for executing the finite element method on a local workstation in the absence of network access. This application is comparable to current, local workstation based finite element packages. However, it differs fundamentally from standard packages since the application itself, and its objects, are adapted to support distributed execution of the analysis task. Basic aspects of an object-oriented framework for the development of applications which can be used in similar distributed collaboratories are described in this paper. An important feature of this framework is its application-centred design. This means that an application can contain any number of engineering models, where the models are formed by the collection of objects according to semantic views within the application. This is achieved through very flexible classes Application and Model, which are described in detail. The advantages of the application-centred design approach is demonstrated with reference to the design of steel structures, where the finite element analysis model, member design model and connection design model interact to provide the required functionality.},

  abstract  = {The promise of lower costs for sensors that can be used for construction inspection means that inspectors will continue to have new choices to consider in creating inspection plans. However, these emerging inspection methods can require different activities, resources, and decisions such that it can be difficult to compare the emerging methods with other methods that satisfy the same inspection needs. Furthermore, the context in which inspection is performed can significantly influence how well certain inspection methods are suited for a given set of goals for inspection. Context information, such as weather, security, and the regulatory environment, can be used to understand what information about a component should be collected and how an inspection should be performed. The research described in this paper is aimed at developing an approach for comparing and selecting inspection plans. This approach consists of (1) refinement of given goals for inspection, if necessary, in order to address any additional information needs due to a given context and in order to reach a level of detail that can be addressed by an inspection activity; (2) development of constraints to describe how an inspection should be achieved; (3) matching of goals to available inspection methods, and generation of activities and resource plans in order to address the goals; and (4) selection of an inspection plan from among the possible plans that have been identified. The authors illustrate this approach with observations made at a local construction site.},

Based on empirical data collected from 74 US construction firms, the analyses provide evidence that IT has a positive impact on overall firm performance, schedule performance, and cost performance. Firm performance is a composite score of several metrics of performance: schedule performance, cost performance, customer satisfaction, safety performance, and profit. No relationship is found between IT utilization and customer satisfaction, safety, or profit, although this may be due to limitations of the study given strong correlations between IT utilization and cost and schedule performnance. The empirical evidence of positive association between performance and IT use provided by this research is significant to both construction practice and research literature. This evidence should encourage firms to adopt and invest in IT tools.},

  abstract  = {This paper describes a research project that addresses the difficulties in dealing with regulatory documents such as national and regional codes. These documents tend to be voluminous, heavily cross-referenced, possibly ambiguous and even conflicting at times. There are often multiple documents that need to be consulted and satisfied; however it is a difficult task to locate all of the relevant provisions. In addition, sections dealing with the same or similar conceptual ideas sometimes lay down conflicting requirements. We propose a framework for regulation representation, analysis and comparison with emphasis on the extraction of similarities between provisions. We focus on accessibility regulations, whose intent is to provide the same or equivalent access to a building and its facilities for disabled persons. An XML regulatory repository is developed to extract structural as well as non-structural features from government regulations to help user understanding and computational analysis. A similarity analysis is performed between different sources of regulations. In order to achieve a better comparison between provisions, we employ a combination of feature matching and structural analysis. Results are shown on comparisons between American and European codes, as well as on the domain of electronic-rulemaking.},

  abstract  = {The general motivation of this research is to develop software to support the handling of the increased complexity of architectural design. In this paper we describe a system providing general support during the whole process. Instead of only developing design tools we are also addressing the problem of the operating environment of these tools. We conclude that design tools have to be integrated in an open, modular, distributed, user friendly and efficient environment. Two major fields have to be addressed - the development of design tools and the realisation of an integrated system as their operation environment. We will briefly focus on the latter by discussing known technologies in the field of information technology and other design disciplines that can be used to realise such an environment. Regarding the first subject we have to state the need of a detailed tool specification. As a solution we suggest a strategy where the tool functions are specified on the basis of a transformation, where a hierarchical process model is mapped into specifications of different design tools realising appropriate support for all sub-processes of architectural design. Using this strategy the main steps to develop such a support system are: implementation of a framework as basis for the integrated design system decision whether the tool specification are already implemented in available tools in this case these tools can be integrated using known methods for tool coupling otherwise new design tools have to be developed according to the framework},

  abstract  = {The steel structure design codes require to check up the member strength when evaluating plastic deformations. The model of perfectly plastic material is accepted. The strength criteria for simple cross-sections (I section, etc.) of steel members are given in design codes. The analytical strength criteria for steel cross-sections and numerical approaches based on stepwise procedure are investigated in many articles. Another way for checking the carrying capacity of cross-sections is the use of methods that are applied for defining strain-deformed state of elastic perfectly plastic systems. In this paper non-iterative methods are suggested for checking strength of cross-sections. Carrying capacity of cross section is verified according to extremum principle of plastic fail under monotonically loading and the strain-deformed state of cross-section is defined according to extremum energy principals of elastic potential of residual stresses and complementary work of residual displacements. The mathematical expressions of these principals for discrete cross-section are formulated as problems of convex mathematical programming. The cross-section of steel member using finite element method is divided into free form plane elements. The constant distribution of stresses along the finite element is accepted. The relationships of finite elements for static formulation of the problem are formed so, that kinematics formulation relationships could be obtained in a formal way using the theory of duality. Numerical examples of determination of cross-section strength, composition of interactive curves and composition of moment-curvature curves for different axial force levels are presented.},

The objectives are to avoid accidents, flooding, pollutions through combined sewer overflows and excessive operation and maintenance costs. Fuzzy logic was proved to be a promising approach, flexible and easy accepted, because it includes the expert knowledge. Fuzzy control system proposed is robust and also easy to understand and modified. It offers to the operator the possibility to participate directly in the system control, combining the results of the modern optimization techniques with the experience and knowledge accumulated in time by experts. Thus, the control of urban sewer system can be well solved by implementing an intelligent control system, based on available information (fuzzy) and on expert's experience. An important feature of this fuzzy logic system is its capability to elaborate a control decision even in situations that were not considered in the design phase of the urban network.},

  abstract  = {The development of the qualitative methods of investigation of dynamic systems, suggested by the authors, is the effective means for identification of dynamic systems. The results of the extensive investigations of the behaviour of linear dynamic systems and symmetrical system with double well potential under polyharmonic excitation are given in the paper. Phase space of dynamic systems is multi-dimensional. Each point of this space is characterized by not less than four co-ordinates. In particular: displacement, velocity, acceleration and time. Real space has three dimensions. It is more convenient for the analysis. We consider the phase space as limited to three dimensions, namely displacement, velocity and acceleration. Another choice of parameters of phase planes is also possible [1, 2]. Phase trajectory on a plane is of the greatest interest. It is known that accelerations of points are more sensitive to deviations of oscillations from harmonic ones. It is connected with the fact that power criteria on it are interpreted most evidently. Besides, dependence is back symmetric relative to axis of the diagram of elastic characteristic. Only the phase trajectories allow establishing a type and a level of non-linearity of a system. The results of the extensive investigations of the dynamic systems behaviour under polyharmonic excitation are given in the paper. The use of the given phase trajectories enables us to determine with a high degree of reliability the following peculiarities: - presence or absence of non-linear character of behaviour of a dynamic system; - type of non-linearity; - type of dynamic process (oscillations of the basic tone, combinative oscillations, chaotic oscillations.). Unlike existing asymptotic and stochastic methods of identification of dynamic systems, the use of the suggested technique is not connected with the use of a significant amount of computing procedures, and also it has a number of advantages at the investigation of complicated oscillations.},

  abstract  = {In this paper a meshless component is presented, which internally uses the common meshless interpolation technique >Moving Least Squares<. In contrast to usual meshless integration schemes like the cell quadrature and the nodal integration in this study integration zones with triangular geometry spanned by three nodes are used for 2D analysis. The boundary of the structure is defined by boundary nodes, which are similar to finite element nodes. By using the neighborhood relations of the integration zones an efficient search algorithm to detected the nodes in the influence of the integration points was developed. The components are directly coupled with finite elements by using a penalty method. An widely accepted model to describe the fracture behavior of concrete is the >Fictitious Crack Model< which is applied in this study, which differentiates between micro cracks and macro cracks, with and without force transmission over the crack surface, respectively. In this study the crack surface is discretized by node pairs in form of a polygon, which is part of the boundary. To apply the >Fictitious Crack Model< finite interface elements are included between the crack surface nodes. The determination of the maximum principal strain at the crack tip is done by introducing an influence area around the singularity. On a practical example it is shown that the included elements improve the model by the transmission of the surface forces during monotonic loading and by the representation of the contact forces of closed cracks during reverse loading.},

  abstract  = {In this paper we revisit the so-called Bergman kernel method (BKM) for solving conformal mapping problems. This method is based on the reproducing property of the Bergman kernel function. The main drawback of this well known technique is that it involves an orthonormalization process and thus is numerically unstable. This difficulty can be, in some cases, overcome by using the Maple system, which makes no use of numeric quadrature. We illustrate this implementation by presenting a numerical example. The construction of reproducing kernel functions is not restricted to real dimension 2. Results concerning the construction of Bergman kernel functions in closed form for special domains in the framework of hypercomplex function theory suggest that BKM can also be extended to mapping problems in higher dimensions, particularly 3-dimensional cases. We describe such a generalized BKM-approach and present numerical examples obtained by the use of specially developed software packages for quaternions.},

Dabei zeigt sich, daß mathematische Modelle auf der Grundlage von Extremalprinzipien und unter Einbeziehung der mathematischen Optimierung effektiv und hinreichend universell formuliert werden k{\"o}nnen. Wie Beispielrechnungen zeigen, ist die Beurteilung der Tragf{\"a}higkeit unter Ber{\"u}cksichtigung von Deformationsbegrenzungen von entscheidender Bedeutung, um Fehleinsch{\"a}tzungen der Tragsicherheit zu vermeiden.},

  abstract  = {In der j{\"u}ngeren Vergangenheit haben die Entwicklungen von neuen Programmen und der Rechentechnik zu radikalen Ver{\"a}nderungen in den Methoden der Berechnung von ingenieurtechnischen Bauten gef{\"u}hrt. An erster Stelle sind hier die Matrizenmethoden f{\"u}r notwendige Berechnungen der Aufgaben anzuf{\"u}hren, welche eine kompakte und allgemeine Form der Aufschreibung von Gleichungen gestatten und geeignet f{\"u}r die Bearbeitung an Computern sind. Die elektronischen Maschinen wurden damit bef{\"a}higt nicht nur Systeme linear-algebraischer Gleichungen mit hundert oder tausend von Unbekannten zu l{\"o}sen, sonder auch die Bearbeitung von Differentialgleichungen, sowie die Formierung dieser Gleichungen zu {\"u}bernehmen. Damit {\"u}bernehmen die Computer den Grossteil des Prozesses der Berechnung und der Projektierung einer Konstruktion. Zweifellose Aktualit{\"a}t haben die Fragen {\"u}ber die Benutzung dieser Eigenschaften f{\"u}r die Aufgaben der Bauinformatik und Baumechanik. Diesen ist der vorliegende Artikel gewidmet. In der Praxis der Projektierung kommen oft komplexe Stabsysteme und zylindrische-gefaltete Fl{\"a}chensysteme vor. Dabei ist zu ber{\"u}cksichtigen: die Verschiebung in Stabsystemen, ihre elastischen Gr{\"u}ndungen und die auftretenden l{\"a}ngs- und querlaufenden Biegungen sowie harmonische Schwingungen. In diesem Artikel wird ein universeller Algorithmus zur Ausarbeitung von Matrizen f{\"u}r H{\"a}rte- und Festigkeitsbetrachtungen f{\"u}r St{\"a}be vorgestellt. Der entwickelte Algorithmus erlaubt die Berechnung von komplizierten Stabsystemen, die in der Praxis weit verbreitet sind. F{\"u}r die Ausarbeitung der Matrizen f{\"u}r die Festigkeitsbetrachtung wurde die symbolische Programmiersprache MAPLE benutzt. Weiterhin zeigt dieser Artikel die Berechnung von gefalteten Fl{\"a}chensystemen unter Verwendung des diskret- kontinuierlichen Modells von W. S. Wlasow, mit Hilfe eines universellen Algorithmus auf. F{\"u}r die Aufstellung der Matrix f{\"u}r Festigkeitsbetrachtung werden als Systemeinstellungen die Schichtformierung und der Ausschluss nach Gauss vorgeschlagen. Am Ende des Artikels werden Beispiele f{\"u}r die Berechnung von komplizierten Konstruktion aufgef{\"u}hrt.},

Im Ergebnis dieser Untersuchungen zeigt sich, dass sich die Versagenswahrscheinlichkeit signifikant erh{\"o}ht, wenn stochastische Tragwerkseigenschaften in Ansatz gebracht werden. Die gr{\"o}ßte Bedeutung besitzt dabei die Zuf{\"a}lligkeit der Zugfestigkeit der Bewehrung. Alle anderen Zufallsgr{\"o}ßen beeinflussen die Versagenswahrscheinlichkeit nur in ihrer Gesamtheit, einzeln betrachtet sind sie nahezu bedeutungslos.

  abstract  = {F{\"u}r die Analyse von Tragwerken sowohl des Stahlbaus als auch des Massivbaus er{\"o}ffnet die nationale und internationale Normengebung in zunehmendem Maße die Anwendung physikalisch nichtlinearer Berechnungsmodelle. Es ist zu erwarten, daß neben dem traditionellen elastischen Berechnungsmodell das linearelastisch-idealplastische Materialmodell in die Tragwerksanalyse Eingang finden wird. W{\"a}hrend bei den traditionellen Berechnungsverfahren auf der Grundlage der Elastizit{\"a}tstheorie hinreichende Erfahrungen durch die Planungspraxis bestehen und umfangreiche Untersuchungen zur dabei erreichten Sicherheit vorliegen, stellen die nichtlinearen Berechnungsmethoden sowohl in mechanischer als auch in sicherheitstheoretischer Hinsicht ein neues Erfahrungsfeld dar. Im vorliegenden Beitrag werden aus der Vielzahl der anstehenden Probleme folgende Teilprobleme behandelt: Bestimmung der Versagenswahrscheinlichkeit elasto-plastischer Tragsysteme nach dem Kriterium der plastischen Grenzlast Ermittlung stochastischer Eigenschaften des plastischen Grenzlastparameters elasto-plastischer Tragsysteme. Die L{\"o}sung des mechanischen Problems geschieht {\"u}ber eine lineare Optimierungsaufgabe, die nach dem statischen Theorem der plastischen Grenzlast formuliert ist. Als stochastische Methode wird die Simulation angewandt, die zum einen auf einer zuf{\"a}lligen Erzeugung der Realisierungen (stochastische Simulation) und zum anderen auf einer planm{\"a}ßigen Erzeugung der Realisierungen (konstruktive Simulation) beruhen kann.

  abstract  = {In der vorliegenden Arbeit geht es um die Anwendung von biorthogonalen Waveletsystemen in der Parameteridentifikation. Es sollen Grundlagen geschaffen werden, um bei der Auswertung dynamischer Experimente derartige Wavelets und damit die schnelle Wavelet-Transformation (FWT) systematisch und effektiv zu nutzen. Zu diesem Zweck wird von den Waveletfiltern ein System von Verbindungskoeffizienten abgeleitet. Mit deren Hilfe erfolgen die Projektionen von Operatoren, insbesondere die von Differentiations- und Integrationsoperatoren, in die entsprechenden Wavelet-R{\"a}ume. S{\"a}mtliche Verbindungskoeffizienten k{\"o}nnen rekursiv und in endlich vielen Schritten exakt berechnet werden. Ausgehend von den dynamischen Krafteinwirkungen und den gemessenen Reaktionsbeschleunigungen oder Reaktionsgeschwindigkeiten bez{\"u}glich der einzelnen Freiheitsgrade k{\"o}nnen dann unbekannte Steifigkeiten und D{\"a}mpfungen identifiziert werden. Dazu erfolgt nach entsprechenden Wavelet-Zerlegungen aller relevanten Zeitsignale ein Abgleich auf den einzelnen Frequenzb{\"a}ndern. Dieser f{\"u}hrt insbesondere zu einem System von linearen Matrizengleichungen zur Bestimmung der unbekannten Parameter. Vorgeschlagen wird im Falle einer gr{\"o}ßeren Zahl von Freiheitsgraden und Parametern, ein mehrstufiges Optimierungsverfahren anzuwenden. Gegen{\"u}ber Identifikationsverfahren im Zeitbereich werden aufwendige numerische Quadraturverfahren und die daraus resultierenden Fehlerquellen und Stabilit{\"a}tsprobleme vermieden. Gegen{\"u}ber Verfahren im Frequenzbereich, die ausschließlich mit Hilfe der FFT formuliert werden, sind St{\"o}rungen in den Randspektren besser beherrschbar und eliminierbar. Außerdem werden mit einem FWT-Verfahren einfachere Denoising-Algorithmen anwendbar. Letztendlich wird im Vergleich zu einem FFT-Verfahren ein sp{\"a}terer {\"U}bergang zur Identifikation nichtlinearer MDOF-Systeme methodisch erleichtert.},

Da innerhalb von IFC-Geb{\"a}udemodellen Bauteile oft das Resultat mehrerer boolescher Operationen sind (z.B. um mehrere Fenster{\"o}ffnungen von einer gegebenen Wand abzuziehen), wurde der Algorithmus von Hubbard angepasst, sodass mehrere boolesche Operationen gleichzeitig berechnet werden k{\"o}nnen.

  abstract  = {A market analysis conducted by Gartner Dataquest in August 2001 has shown the typical characteristics of the AEC design process. High volatility in membership of AEC design groups and members dispersed over several external offices is the common collaboration scenario. Membership is most times short lived, compared to the overall duration of the process. A technical solution has to take that into account by making joining and leaving a collaborative work group very easy. The modelling of roles of collaboration between group members must be based on a commonly understood principle like the publisher / subscriber model, where the individual that is responsible for the distribution of vital information is clear. Security issues and trust in the confidentiality of the system is a central concern for the acceptance of the system. Therefore, keeping the subset of data that will be published under the absolute control of the publisher is a must. This is not the case with server-based scenarios, sometimes even due to psychological reasons. A loosely bound Peer-to-Peer network offers advantages over a server-based solution, because of less administrative overhead and simple installation procedures. In a peer-to-peer environment, a publish/subscribe role model can be more easily implemented. The publish/subscribe model matches the way AEC processes are modelled in real world scenarios today, where legal proof of information exchange between external offices is of high importance. Workflow management systems for small to midsize companies of the AEC industry may adopt the peer-to-peer approach to collaboration in the future. Further investigations are being made on the research level (WINDS) by integrating the viewer and redlining application Collaborate! into a collaborative environment.},

The strategic use of Information and Communication Technologies (ICT) has enabled this goal to be completed more effectively. Two issues require addressing, the technology itself and the implementation factors of the technology. Such implementation factors should consider, among other factors, the legal and contractual issues associated with the use of ICT, training requirements and its effects on the organisational culture. To date the legal and contractual issues have not been extensively covered, and it is recognised that the technologies have not been properly covered by any recognised legal and contractual practices. This in turn is threatening to inhibit the growth and prosperity of the use of the technology on construction projects.

  abstract  = {The rise of concurrent engineering in construction demands early team formation and constant communication throughout the project life cycle, but educational models in architecture, engineering and construction have been slow to adjust to this shift in project organization. Most students in these fields spend the majority of their college years working on individual projects that do not build teamwork or communication skills. Collaborative Design Processes (CDP) is a capstone design course where students from the University of Illinois at Urbana-Champaign and the University of Florida learn methods of collaborative design enhanced by the use of information technology. Students work in multidisciplinary teams to collaborate from remote locations via the Internet on the design of a facility. An innovation of this course compared to previous efforts is that students also develop process designs for the integration of technology into the work of multidisciplinary design teams. The course thus combines both active and reflective learning about collaborative design and methods. The course is designed to provide students the experience, tools, and methods needed to improve design processes and better integrate the use of technology into AEC industry work practices. This paper describes the goals, outcomes and significance of this new, interdisciplinary course for distributed AEC education. Differences from existing efforts and lessons learned to promote collaborative practices are discussed. Principal conclusions are that the course presents effective pedagogy to promote collaborative design methods, but faces challenges in both technology and in traditional intra-disciplinary training of students.},

Die Entwurfsmethode wird anhand einer Systemregelung f{\"u}r eine solarthermische Anlage mit 120m2 Kollektorfl{\"a}che (SolarThermie2000 Anlage) demonstriert, bei der ein vernetztes Regelungssystem mit Internet-Integration zum Einsatz kommt. Das Regelungssystem verf{\"u}gt seinerseits {\"u}ber ein Betriebssystem (schlankes embedded linux system), das die Kommunikation nach aussen gestattet. Das Regelungssystem vef{\"u}gt somit {\"u}ber Klima- bzw Strahlungsdaten, die f{\"u}r den Regelungsprozess von Bedeutung sind. Die externen Informationen k{\"o}nnen einerseits zur >Einsparung< von Sensorik genutzt werden, andererseits gestatten sie den Einsatz von pr{\"a}diktiver Regelungsmethodik, um den fossilen (Nachheiz-) Energieeinsatz zu minimieren. Mit Hilfe von simulationstechnischen Systemstudien kann ein adaptives Verhalten des Regelungssystems erprobt werden, das eine selbstst{\"a}ndige Strecken- identifikation realieren kann. Beispielsweise soll beim n{\"a}her beschriebenen solarthermischen System die Totzeit bestimmt werden, die sich infolge der Verrohrung zwischen Speicher und Entladegruppe ergibt. Der Betrieb der Entlade- pumpe wird einerseits in Abh{\"a}ngigkeit der Verf{\"u}gbarkeit des Pufferwassers erfolgen, andererseits in Abh{\"a}ngigkeit des erwarteten Zapfvolumens durch den Verbraucher. Die vernetzten Regelungssysteme, die auf Basis der Simulationsmodelle ent- wickelt werden, sollen k{\"u}nftig die gesamte Energieflußanalyse des Geb{\"a}udes realisieren, wobei eine transparente Darstellung des Systemverhaltens auf Basis einer Internet Visualisierung erfolgt. Der Betreiber und Nutzer wird unmittel- bar durch die Online Dienste (SMS,Email,Fax) {\"u}ber das (fehlerhafte) Anlagen- verhalten informiert. Gerade die sensitiven regenerativen Systeme neigen durch ihre Komplexit{\"a}t zu St{\"o}rungen, die oftmals nicht erkannt werden, weil die konventionellen Teilsysteme (z.B.

  abstract  = {The subject of this paper is to explore and evaluate the semi-analytical, analytical and numerical versions of the finite strip method (FSM) for static, dynamic and stability analyses of complex thin-walled structures. Many of bridge superstructures, some roof and floor structures, reservoirs, channels, tunnels, subways, layered shells and plates etc. can be analysed by this method. In both semi-analytical and analytical variants beam eigenvalue vibration or stability functions, orthogonal polynomials, products of these functions are used as longitudinal functions of the unknowns. In the numerical FSM spline longitudinal displacement functions are implemented. In the semi-analytical and numerical FSM conventional transverse shape functions for displacements are used. In the analytical FSM the accurate function of the strip normal displacement and the plane stress function are applied. These three basic variants of the FSM are compared in quality and quantity in view to the following: basic ideas, modelling, unknowns, DOF, a kind and order of the strips, longitudinal and transverse displacement and stress functions, compatibility requirements, boundary conditions, ways for obtaining of the strip stiffness and load matrices, a kind and size of the structure stiffness matrix and its band width, mesh density, necessary number of terms in length, accuracy and convergence of the stresses and displacements, approaches for refining results, input and output data, computer resources used, application area, closeness to other methods, options for future development. Numerical example is presented. Advantages and shortcomings are pointed. Conclusions are given.},

  abstract  = {Computational Steering provides methods for the integration of modeling, simulation, visualization, data analysis and post processing. The user has full control over a running simulation and the possibility to modify objects (geometry and other properties), boundary conditions and other parameters of the system interactively. The objective of such a system is to explore the effects of changes made immediately and thus to optimize the target problem interactively. We present a computational steering based system for fluid flow problems in civil engineering. It is based on three software components as shown in figure 1. The modeler is the CAD-system AutoCAD, which offers a powerful programming interface allowing an efficient access to the geometric data. It also offers convenient manipulators for geometric objects. The simulation kernel is a Lattice-Boltzmann (LB) solver for the Navier-Stokes equations, which is especially suitable for instationary flows in complex geometries. For the visualization and postprocessing we use the software tool AVS, which provides a powerful programming interface and allows the efficient visualization of flow fields. These three components are interconnected through two communication modules and three interfaces as depicted in figure 1. Interface 1 is responsible for the transformation of the modified system for the simulation kernel, interface 2 is responsible for the proper preparation of the simulation data whereas interface 3 transforms the data from the modeler into a format suitable for the visualization system. The whole system is synchronized by the two communication modules.},

  abstract  = {Designing lightings in a 3D-scene is a general complex task for building conception as it is submitted to many constraints such as aesthetics or ergonomics. This is often achieved by experimental trials until reaching an acceptable result. Several rendering softwares (such as Radiance) allow an accurate computation of lighting for each point in a scene, but this is a long process and any modification requires the whole scene to be rendered again to get the result. The first guess is empirical, provided by experience of the operator and rarely submitted to scientific considerations. Our aim is to provide a tool for helping designers to achieve this work in the scope of global illumination. We consider the problem when some data are asked for : on one hand the mean lighting in some zones (for example on a desktop) and on the other hand some qualitative information about location of sources (spotlights on the ceiling, halogens on north wall,...). The system we are conceiving computes the number of light sources, their position and intensities, in order to obtain the lighting effects defined by the user. The algorithms that we use bind together radiosity computations with resolution of a system of constraints.},

  abstract  = {Poland is not situated in any seismic region of the earth, however there are still areas were underground mining is being conducted. In these areas, so-called 'paraseismic tremors', are very frequent phenomena. In the situation when a building examination is realized in order to define its safety, it is necessary to make a complete analysis, in which an influence of tremors should be included. To decide if a building is able to carry out any dynamic loads or not, it is necessary to compute its dynamic characteristics, i.e. natural frequencies. It is not possible using any standard techniques. After diagnosis a building in situ by an expert, computer techniques together with specialized software for dynamic, static, and strength analyses become a suitable tool. In this paper a special attention was paid to a typical twelve-store WGP (Wroclaw Great Plate) prefabricated building, concerning special type of joints. During dynamic actions these joints have a decisive influence on building's behavior. Paraseismic tremors are especially dangerous for these buildings and can be the reason of pre-failure states. It can be difficult and very expensive to prepare laboratory investigations of the part of a building or of a separate joint; therefore the computer modeling suitable to investigate behavior of such elements and whole buildings under different kinds of loads was used.},

  abstract  = {The paper describes a development of the analytical finite strip method (FSM) in displacements for linear elastic static analysis of simply supported at their transverse ends complex orthotropic prismatic shell structures with arbitrary open or closed deformable contour of the cross-section under general external loads. A number of bridge top structures, some roof structures and others are related to the studied class. By longitudinal sections the prismatic thin-walled structure is discretized to a limited number of plane straight strips which are connected continuously at their longitudinal ends to linear joints. As basic unknowns are assumed the three displacements of points from the joint lines and the rotation to these lines. In longitudinal direction of the strips the unknown quantities and external loads are presented by single Fourier series. In transverse direction of each strips the unknown values are expressed by hyperbolic functions presenting an exact solution of the corresponding differential equations of the plane straight strip. The basic equations and relations for the membrane state, for the bending state and for the total state of the finite strip are obtained. The rigidity matrix of the strip in the local and global co-ordinate systems is derived. The basic relations of the structure are given and the general stages of the analytical FSM are traced. For long structures FSM is more efficient than the classic finite element method (FEM), since the problem dimension is reduced by one and the number of unknowns decreases. In comparison with the semi-analytical FSM, the analytical FSM leads to a practically precise solution, especially for wider strips, and provides compatibility of the displacements and internal forces along the longitudinal linear joints.},

In general, several aspects of approximation and interpolation are only well understood by using methods of complex analysis. It seems natural to extend these techniques to higher dimensions by using Clifford Analysis methods or, more specific, in lower dimensions 3 or 4, by using tools of quaternionic analysis. One starting point for such attempts has to be the suitable choice of complete orthonormal function systems that should replace the holomorphic function systems used in the complex case. The aim of our contribuition is the construction of a complete orthonormal system of monogenic polynomials derived from a harmonic function system by using sistematically the generalized quaternionic derivative},

The Bridge has a rather long design service life of 100 years. Because of its large size and long span length, its design is not covered by any existing codes or standards worldwide. The focus of the paper is to introduce the data acquisition, transfer, processing and management systems. The instrumentation and communications infrastructure and devices will be presented in some details along with the data processing and management systems and techniques. Teams of engineers and researchers use the collected data to verify the analysis and design assumptions and parameters as well as investigate the short-term and long-term behaviour and health of the Bridge. The collected data are also used in furthering research activities in the field of bridge engineering and in elevating our knowledge about behaviour, reliability and durability of such complex structures, their components and materials.},

However, in many situations, historical data are extracted and preprocessed for knowledge discovery based on time-consuming and problem-specific data preparation solutions, which often results in inefficiencies and inconsistencies. To overcome the problem, we are working on the development of a new data fusion methodology, which is designed to provide timely and consistent access to historical data for efficient and effective management knowledge discovery. The methodology is intended to be a new bridge between historical databases and data analysis techniques, which shields project managers from complex data preparation solutions, and enables them to use discovered knowledge for decision making more conveniently.

LCA methods had to be developed for buildings because of their complexity, their long life duration and through a large number of actors who are involved. This was realized by integrating life cycle analysis, life cycle costing and building product models in integrated LCA models. However the use of such models leads to difficulties. The principal ones are the uncertainty treatment in LCA models and the lack of experience of practitioners who are not LCA specialists. Answers to these problems are the management of uncertainty and the development of simplified models for building design, construction and operation. This can be achieved with the mean of experimental plans or Monte Carlo simulation. The paper will focus on how these techniques can be used, what are their possibilities and disadvantages, particularly concerning the development of simplified models.},

  abstract  = {The construction of a new building interferes with the existent environment. A careful aesthetic study must be made at an early stage in the design and the visualization of a three-dimensional (3D) model of the structure is the best way to analyse it. As some structures presents a complex shape is difficult to execute a 3D model as well as the specific drawings. Using traditional graphical systems, the execution of deck specific drawings is extremely time consuming and the 3D deck model gives an approximation only of the exterior shape of the deck. The modelling scheme proposed here allows the automation of the geometric design phases related to the deck bridge element using as a means of integration a geometric database representative of the real deck shape. This concept was implemented in a computer program. This application is an important support in the process design namely at the conceptual and graphical stages. The computer application provides an important tool to the bridge designer particularly at the conceptual stage, as it allows aesthetic and structural evaluation of the bridge at an early stage in the design. The geometric modelling process and graphical results of a case study are presented.},

  abstract  = {In the field of Civil Engineering, the content of reinforcement concrete design course (RC course) has complicated design procedures and many difficult specifications to recognize, so most of the students regard the RC course a tough course, and teachers very often find the class time insufficient. Also, teachers of the RC course usually spend a lot of time in organizing the examinations for handling tedious calculations and complicated logical reasoning. Furthermore, correcting examination papers with partial scoring takes even more time of the teacher's. Therefore, the objective of this research is to design and develop a partial scoring assessment system to meet the needs in engineering design courses, such as the RC course. This assessment system can generate test items with variable parameters. It also supports inference diagnosis on the examinee's misconceptions and gives partial scores in grading the examination. In this research, the example test subject is the analysis of rectangular reinforced concrete beam with single layer steel bars.},

  abstract  = {An important feature of the 2003 SARS outbreak in Canada, Singapore, and Hong Kong was that many health care workers (HCWs) developed SARS after caring for patients with SARS. This has been ascribed to inadequate or ineffective patient isolation. However, it is difficult for dense cities to provide sufficient isolation facilities within a short period of time. This has raised concerns from the public for new strategies in the planning and design of isolation facilities. Considering that SARS or other infectious diseases could seriously damage our society's development, isolation facilities that could be rapidly and economically constructed with appropriate environmental controls are essential. For this reason, the design team of the Department of Architecture collaborated with a special task force from the Faculty of Medicine, who are the frontline medical officers treating the SARS patients, to design Rapidly Assembled Isolation Patient Wards. Both architecture and medicine are well established disciplines, but they have little in common in terms of the mode of knowledge construction and practice. This induced much intellectual exploration and research interest in conducting this study. The process has provided an important reference for cross disciplinary studies between the architectural and medical domains.},

  abstract  = {Usually, the co-ordination of design and planning tasks of a project in the construction industries is done in a paper based way. Subsequent modifications have to be handled manually. The effects of modifications cannot be determined automatically. The approach to specify a complete process model before project start does not consider the requirements of the construction industries. The effort of specification at the beginning and during the process (modifications) does not justify the use of standard process model techniques. A new approach is presented in the according paper. A complete process model is deducted on the basis of a core. The core consists of process elements and specific relations between them. Modifications need to be specified in the core only. The effort of specification is therefore reduced. The deduction of the complete process is based on the graph theory. Algorithms of the graph theory are also used to determine the effects of modifications during project work.},

  abstract  = {In this study a simple effective procedure practically based upon the FEM for determination of the dynamic stress intensity factor (DSIF) depending on the input frequency and using an advanced strain energy release evaluation by the simultaneous release of a set of fictitious nodal spring links near the crack tip is developed and applied. The DSIF is expressed in terms of the released energy per unit crack length. The formulations of the linear fracture mechanics are accepted. This technique is theoretically based upon the eigenvalue problem for assessment of the spring stiffnesses and on the modal decomposition of the crack shape. The inertial effects are included into the released energy. A linear elastic material, time-dependent loading of sine type and steady state response of the structure are assumed. The procedure allows the opening, sliding and mixed modes of the structure fracture to be studied. This rational and powerful technique requires a mesh refinement near the crack tip. A numerical test example of a square notched steel plate under tension is given. Opening mode of fracture is studied only. The DSIF is calculated using a coarse mesh and a single node release for the released energy computation as well a fine mesh and simultaneous release of four links for more accurate values. The results are analyzed. Comparisons with the known exact results from a static loading are presented. Conclusions are derived. The values of the DSIF are significantly larger than the values of the corresponding static SIF. Significant peaks of the DSIF are observed near the natural frequences. This approach is general, practicable, reliable and versatile.},

This paper reports on progress of a project, which aims to achieve better integrated building and systems control modeling in building performance simulation by run-time coupling of distributed computer programs. These requirements motivate the use of the Common Object Request Broker Architecture (CORBA), which offers sufficient advantage than communication within simple abstraction. However, set up highly available applications with CORBA is hard. Neither control modeling software nor building performance environments have simple interface with CORBA objects. Therefore, this paper describes an architectural solution to distributed control and building performance software tools with CORBA objects. Then, it explains how much the developement of CORBA based distributed building control simulation applications is difficult. The paper finishes by giving some recommendations.},

  abstract  = {This paper reports on the latest results in the development of a new approach for simulating the thermal behavior of buildings that overcomes the limitations of conventional heat-transfer simulation methods such as FDM and FEM. The proposed technique uses a coarse-grain approach to model development whereby each element represents a complete building component such as a wall, internal space, or floor. The thermal behavior of each coarse-grain element is captured using empirical modeling techniques such as artificial neural networks (ANNs). The main advantages of the approach compared to conventional simulation methods are: (a) simplified model construction for the end-user; (b) simplified model reconfiguration; (c) significantly faster simulation runs (orders of magnitude faster for two and three-dimensional models); and (d) potentially more accurate results. The paper demonstrates the viability of the approach through a number of experiments with a model of a composite wall. The approach is shown to be able to sustain highly accurate longterm simulation runs, if the coarse-grain modeling elements are implemented as ANNs. In contrast, an implementation of the coarse-grain elements using a linear model is shown to function inaccurately and erratically. The paper concludes with an identification of on-going work and future areas for development of the technique.},
