  abstract  = {The design of building projects involves several types of resources such as architects, structural engineers, mechanical engineers, electrical engineers, and draftsmen, among others. For design firms to stay in business in this very competitive market, they need to manage their resources in a way that improves productivity and cost effectiveness. This task, however, is not simple and requires thorough analysis of process-level operations, resource use, and productivity. Typically, these operational aspects are the responsibility of the design office manager who assigns available resources to the different design projects to save time and lower design expenses. It is noted that limited studies have been carried out in the literature to model overall organizational operations and behavioral aspects, particularly in firms specialized in the design of building projects. In an effort to simplify the modeling process, a simplified modeling and simulation tool is used in this research. A simulation model representing an actual design office was developed assuming that the office performs designs for small, medium, and large size building projects. The developed model was used to simulate several alternatives and examine various resource assignment strategies. The simulation was conducted over ten years and the resulting productivity and income was measured.},

  abstract  = {From a macroscopic point of view, failure within concrete structures is characterized by the initiation and propagation of cracks. In the first part of the thesis, a methodology for macroscopic crack growth simulations for concrete structures using a cohesive discrete crack approach based on the extended finite element method is introduced. Particular attention is turned to the investigation of criteria for crack initiation and crack growth. A drawback of the macroscopic simulation is that the real physical phenomena leading to the nonlinear behavior are only modeled phenomenologically. For concrete, the nonlinear behavior is characterized by the initiation of microcracks which coalesce into macroscopic cracks. In order to obtain a higher resolution of this failure zones, a mesoscale model for concrete is developed that models particles, mortar matrix and the interfacial transition zone (ITZ) explicitly. The essential features are a representation of particles using a prescribed grading curve, a material formulation based on a cohesive approach for the ITZ and a combined model with damage and plasticity for the mortar matrix. Compared to numerical simulations, the response of real structures exhibits a stochastic scatter. This is e.g. due to the intrinsic heterogeneities of the structure. For mesoscale models, these intrinsic heterogeneities are simulated by using a random distribution of particles and by a simulation of spatially variable material parameters using random fields. There are two major problems related to numerical simulations on the mesoscale. First of all, the material parameters for the constitutive description of the materials are often difficult to measure directly. In order to estimate material parameters from macroscopic experiments, a parameter identification procedure based on Bayesian neural networks is developed which is universally applicable to any parameter identification problem in numerical simulations based on experimental results. This approach offers information about the most probable set of material parameters based on experimental data and information about the accuracy of the estimate. Consequently, this approach can be used a priori to determine a set of experiments to be carried out in order to fit the parameters of a numerical model to experimental data. The second problem is the computational effort required for mesoscale simulations of a full macroscopic structure. For this purpose, a coupling between mesoscale and macroscale model is developed. Representative mesoscale simulations are used to train a metamodel that is finally used as a constitutive model in a macroscopic simulation. Special focus is placed on the ability of appropriately simulating unloading.},

  abstract  = {Current building product models explicitly represent components, attributes of components, and relationships between components. These designer-focused product models, however, do not represent many of the design conditions that are important for construction, such as component similarity, uniformity, and penetrations. Current design and construction tools offer limited support for detecting these construction-specific design conditions. This paper describes the ontology we developed using the manufacturing concept of features to represent the design conditions that are important for construction. The feature ontology provides the blueprint for the additions and changes needed to transform a standard product model into a constructionspecific product model. The ontology formalizes three classes of features, defines the attributes and functions of each feature type, and represents the relationships between features explicitly. The descriptive semantics of the ontology allows practitioners to represent their varied preferences for naming features, specifying features that result from component intersections and the similarity of components, and grouping features that affect a specific construction domain. A software prototype that implements the ontology enables practitioners to transform designer-focused product models into feature-based product models that represent the construction perspective.},

Having been realized, the proposed approach provides for the strongly formalized method and the common software framework to build virtual prototyping applications.

  abstract  = {Buildings require both for construction and, due to their comparatively long life cycle for maintenance, significant raw material and energy resources. So far available knowledge about resource consumption during an entire life cycle of a building is still quite rare, because various criteria affect each other and/or overlay mutually. In this contribution a model based software concept is presented using an integrated approach for life cycle simulation and assessment of buildings. The essential point of the development consists of connecting an IFC compliant product model of a building via the Internet with data bases for the resource and energy requirement of building materials. Furthermore, numerical simulations allow calculating and minimizing the energy consumption, the resource requirement, the waste streams and also the noxious emissions. In the context of this paper we present the first release of software programs for architects and engineers, which help them to evaluate their design decisions objectively in early planning steps. Additionally the usage of the software is demonstrated by a test case study for a real world building. By applying this software in practice a substantial contribution for saving energy and natural resources can be provided in the sense of sustainable and ecological building design.},

This documentation is used as the starting point of the design process, but as the design progresses, it is usually left aside and changes are made incrementally based on the previous design solution. These incremental small changes can lead to a solution that may no longer meet the original requirements. In addition, design is by nature an iterative process and the proposed solutions often also cause evolution in the client requirements. However, the requirements documentation is usually not updated accordingly. Finding the latest updates and evolution of the requirements from the documentation is very difficult, if not impossible. This process can lead to an end result, which is significantly different from the documented requirements. Some important requirements may not be satisfied, and even if the design process was based on agreed-upon changes in the scope and requirements, differences in the requirements documents and in the completed building can lead to well-justified doubts about the quality of the design and construction process...},

According to the statistics from Occupational Safety Health Administration (OSHA), there were 137 crane-related fatalities from 1992 to 2001 in the US. A well-known internet website that keeps track of crane-related accidents (craneaccidents.com), reports 516 accidents and 277 fatalities from 2000 to 2002. These statistics show that even though many measures have been taken to decrease the number of crane-related accidents (Braam, 2002), the number of crane related accidents is still very large. It is important to recognize that each construction related fatality is not only a great human loss but also increases the costs of insurance, lawsuits, and the construction budget due to delay of a project (Paulson 1992)...},

  abstract  = {Die Komplexit{\"a}t des Schweißprozesses und das Verhalten der Werkstoffe infolge des Energieeintrages erfordern eine umfassende Betrachtungsweise. Die Entwicklung von numerischen Modellen und Methoden in den letzten 50 Jahren erm{\"o}glicht die Simulation, Analyse und Optimierung von Schweißverbindungen hinsichtlich Temperatur, Gef{\"u}gestruktur und Eigenspannungen. Eine Differenzierung der Schweißsimulation in Prozess-, Werkstoff- und Struktursimulation gestattet eine gezielte Untersuchung von einzelnen Aspekten. Diese Unterteilung erfordert zum Teil eine starke Abstraktion und Idealisierung der Realit{\"a}t durch geeignete Annahmen und Randbedingungen, die von der zu untersuchenden Fragestellung abh{\"a}ngen. Dadurch wird eine Kalibrierung und Verifikation der Modelle mit Versuchsergebnissen notwendig. Die in dieser Arbeit durchgef{\"u}hrten Untersuchungen besch{\"a}ftigen sich mit wichtigen Fragestellungen hinsichtlich der numerischen Simulation und experimentellen Untersuchung des Temperaturfeldes sowie des Gef{\"u}ge- und Eigenspannungszustandes von MAG-Schweißverfahren an den Werkstoffen Feinkornbaustahl und Duplex-Stahl, CO2-Laserstrahlschweißverfahren am Werkstoff Quarzglas, Trennprozessen von Proben, WIG-Nachbehandlungsverfahren. Hinsichtlich der Naht- und Stoßarten orientierte sich die Arbeit an baupraktisch relevanten Schweißverbindungen sowie Besonderheiten, die sich aus Schweißprozessen und unterschiedlichen Werkstoffen ergeben. Eine Interpretation der numerisch und experimentell ermittelten Ergebnisse erm{\"o}glicht die Ableitung von allgemeing{\"u}ltigen Erkenntnissen zur Ausbildung des Temperaturfeldes, Entstehung von Gef{\"u}gestrukturen und Eigenspannungen. Voraussetzungen f{\"u}r eine realit{\"a}tsnahe Schweißsimulation zur Bestimmung von Temperatur, Gef{\"u}geanteil und Eigenspannung sind neben den Geometriemodellen geeignete numerische Modelle f{\"u}r die Einkopplung der Energie aus dem Schweißprozess und f{\"u}r die Abgabe der Energie durch Konvektion und Strahlung an die Umgebung, zur Beschreibung des thermischen und mechanischen Werkstoffverhaltens im Bereich von Raumtemperatur bis zur Schmelztemperatur.},

  abstract  = {In der vorliegenden Arbeit werden die experimentellen Ergebnisse eigener Untersuchungen an unbewehrtem und bewehrtem polymermodifiziertem Beton unter mehrfach wiederholter Druck- und Zugbeanspruchung vorgestellt und mit den Ergebnissen {\"a}hnlicher Versuche an Normalbeton und hochfestem Beton verglichen. Besondere Aufmerksamkeit wird dabei dem Form{\"a}nderungsverhalten, der Steifigkeitsdegradation und der Energiedissipation sowie dem Kriechverhalten und der Mitwirkung des Betons zwischen den Rissen gewidmet. Die beobachtete signifikante Steifigkeitsdegradation sowie der ausgepr{\"a}gt nichtlineare Zusammenhang zwischen der viskosen Verformung und der elastischen Stauchung zeigen, dass bei der Analyse der Kriech¬aus¬wirkungen des polymermodifizierten Betons auf das Tragverhalten entsprechender Kon¬struktionen neben den Gebrauchslasten auch die w{\"a}hrend der Lastgeschichte aufgetretenen maximalen Beanspruchungssituationen sowie die damit verbundenen Strukturver{\"a}nderungen zu ber{\"u}cksichtigen sind. Auf der Basis der Versuchsergebnisse und der visko-elastisch-plastischen Kontinuumssch{\"a}digungstheorie werden rheologische Modelle zur Beschreibung des zeit- und beanspruchungsabh{\"a}ngigen Tragverhaltens von Betonbauteile vorgeschlagen. Die numerische Umsetzung der vorgeschlagenen Modelle erfolgt unter Ber{\"u}cksichtigung des zeitabh{\"a}ngigen Materialverhaltens des Betons auf der Basis des HAMILTON-Prinzips unter Vernachl{\"a}ssigung der Tr{\"a}gheitskr{\"a}fte. Durch eine zeitliche Diskretisierung kann die Problembeschreibung auf das Prinzip von LAGRANGE vom Minimum des Gesamtpotentials zur{\"u}ckgef{\"u}hrt und als nichtlineare Optimierungsaufgabe formuliert werden. Die Simulation des beanspruchungsabh{\"a}ngigen Tragverhaltens von Stahlbetonverbundquerschnitten verdeutlicht die Qualit{\"a}t und Leistungsf{\"a}higkeit der vorgeschlagenen Modellbildung.},

  abstract  = {In der Arbeit wird ein r{\"a}umliches Materialmodell f{\"u}r den anisotropen Werkstoff Holz vorgestellt. Dessen Leistungsf{\"a}higkeit wird durch Verifikationsrechnungen und die Simulation eigener Versuche aufgezeigt. In diesen Versuchen wurde das Tragverhalten spezieller Schubverbindungselemente der Brettstapel-Beton-Verbundbauweise untersucht. Die Kombination eines Brettstapels mit einer schubfest angeschlossenen Betonplatte ist eine vorteilhafte M{\"o}glichkeit, Schnittholz mit geringem Querschnitt effektiv in biegebeanspruchten Bauteilen einzusetzen. Es werden die Ergebnisse der experimentellen Untersuchungen zu den Schubverbindungselementen Flachstahlschloss und Nutverbindung vorgestellt. Diese zeichnen sich durch eine {\"u}ber die gesamte Plattenbreite kontinuierliche {\"U}bertragung der Schubkraft per Kontaktpressung aus. Vor allem in Brettstapel-Beton-Verbunddecken werden somit ein sehr hoher Verschiebungsmodul sowie eine eminente Tragf{\"a}higkeit erreicht. Um mit numerischen Strukturanalysen die in den Versuchen beobachteten Versagensmechanismen ad{\"a}quat abbilden und realistische Prognosen f{\"u}r das Tragverhalten von Bauteilen oder Verbindungen treffen zu k{\"o}nnen, muss das physikalisch nichtlineare Verhalten aller beteiligter Baustoffe in die Berechnungen einbezogen werden. Im Rahmen der Dissertation wurde ein auf der Plastizit{\"a}tstheorie basierendes Materialmodell f{\"u}r Nadelholz hergeleitet und in das FE-Programm ANSYS implementiert, welches die Mikrostruktur des Holzes als verschmierendes Ersatzkontinuum erfasst. Anhand des anatomischen Aufbaus des inhomogenen, anisotropen und porigen Werkstoffs werden die holzspezifischen Versagensmechanismen und die daraus abgeleiteten konstitutiven Beziehungen erl{\"a}utert. Das ausgepr{\"a}gt anisotrope Tragverhalten von Holz ist vor allem durch erstaunliche Duktilit{\"a}t bei Stauchung, spr{\"o}des Versagen bei Zug- und Schubbeanspruchung und enorme Festigkeitsunterschiede in den Wuchsrichtungen gekennzeichnet. Die Auswirkungen der gr{\"o}ßtenteils unabh{\"a}ngig voneinander auftretenden, mikromechanischen Versagensmechanismen auf die Spannungs-Verformungsbeziehungen wurden durch die Formulierung ad{\"a}quater Ver- resp. Entfestigungsfunktionen in Abh{\"a}ngigkeit der Beanspruchungsmodi erfasst. Das dem Materialmodell zu Grunde liegende mehrfl{\"a}chige Fließkriterium ber{\"u}cksichtigt die Interaktion aller sechs Komponenten des r{\"a}umlichen Spannungszustandes. Die durchgef{\"u}hrten Verifikations- und Simulationsberechnungen belegen, dass der erarbeitete Ansatz sowohl zur Bewertung des Tragverm{\"o}gens als auch zur Beurteilung von Riss- bzw. Sch{\"a}digungsursachen von Holzbauteilen eingesetzt werden kann. Die numerische Simulation er{\"o}ffnet neue, bisher wenig beachtete M{\"o}glichkeiten zur Untersuchung komplexer Holzstrukturen sowie Anschlussdetails und wird sich auf Grund der Aussagekraft und Flexibilit{\"a}t auch im Ingenieurholzbau mehr und mehr gegen{\"u}ber ausschließlich experimenteller Untersuchung durchsetzen.},

  abstract  = {Re-examination of the behaviour of structures can be necessary due to deterioration or changes in the traffic situation during their lifetime. The Finite Element Method (FEM) is widely used in order to accomplish numerical analysis. Considering the development of computer performance, more detailed FEM models can be analyzed, even on site, with mobile computers. To compensate the increasing amount of data needed for the model input, measures need to be taken to save time, by distributing the work. In order to provide consistency to the model, fedback data must be checked upon reception. A local wireless computer network of ultra-portable devices linked together with a computer can provide the coordination necessary for efficient parallel working. Based on a digital model consisting of all data gathered, structural modelling and numerical analysis are performed automatically. Thus, the user is released from the work that can be automatized and the time needed for the overall analysis of a structure is decreased.},

  abstract  = {This research is devoted to promoting the performance-based engineering in wood structure fire. It looks into the characteristic of the material, structural composing and collapse detecting to find out the main factors in the wood structure collapse in fire. The aim of the research is to provide an automatic simulation platform for the complicated circulation. A physically based model for slim member for beams and columns and a frame of multi-physical simulation are provided to implement the system. The physically based model contains material model, structural mechanics model, material mechanics model, as well as geometry model for the compositive simulation. The multi-physical simulation is built on the model and has the capacity to carry out a simulation combining structural, fire (thermal, CFD) and material degradation simulation. The structural and fire simulation rely on two sophisticated software respectively, ANSYS (an FEA software) and FDS (with a core of CFD). Researchers of the paper develop system by themselves to combine the two existing ones. The system has the capability to calculate the wood char to find out the loss of cross-section and to detect the collapse caused in different ways. The paper gives a sample of Chinese traditional house to show how this simulation system works.},

  abstract  = {The development of 3D technologies during the last decades in many different areas, leads us towards the complete 3D representation of planet earth on a high level of detail. On the lowest level we have geographical information systems (GIS) representing the outer layer of our planet as a 3D model. In the meantime these systems do not only give a geographical model but also present additional information like ownership, infrastructure and others that might be of interest for the construction business. In future these systems will serve as basis for virtual environments for planning and simulation of construction sites. In addition to this work is done on the integration of GIS systems with 3D city models in the area of urban planning and thus integration of different levels of detail. This article presents research work on the use of 3D models in construction on the next level of detail below the level of urban planning. The 3D city model is taken as basis for the 3D model of the construction site. In this virtual nD-world a contractor can organize and plan his resources, simulate different variants of construction processes and thus find out the most effective solution for the consideration of costs and time. On the basis of former researches the authors present a new approach for cost estimation and simulation using development technologies from game software.},

  abstract  = {The Bauhaus Summer School series provides an international forum for an exchange of methods and skills related to the interaction between different disciplines of modern engineering science. The 2012 civil engineering course was held in August over two weeks at Bauhaus-Universit{\"a}t Weimar. The overall aim was the exchange of research and modern scientific approaches in the field of model validation and simulation between well-known experts acting as lecturers and active students. Besides these educational intentions the social and cultural component of the meeting has been in the focus. 48 graduate and doctoral students from 20 different countries and 22 lecturers from 12 countries attended this summer school. Among other aspects, this activity can be considered successful as it raised the sensitivity towards both the significance of research in civil engineering and the role of intercultural exchange. This volume summarizes and publishes some of the results: abstracts of key note papers presented by the experts and selected student research works. The overview reflects the quality of this summer school. Furthermore the individual contributions confirm that for active students this event has been a research forum and a special opportunity to learn from the experiences of the researchers in terms of methodology and strategies for research implementation in their current work.},
