The paper summarizes a part of research carried out in ICCI project and provides a current review of ICT infrastructures supporting collaboration. It covers taxonomies, protocols, standards, components, typical subsystems as well as future trends and recommendation for two most important technologies with applications in AEC: (1) EIP (Enterprise information portal) – a single gateway to a company's information, knowledge base, and applications for all actors; (2) RTC (Real-Time Communication and Collaboration technologies) that provide means for asynchronous communication between geographically dislocated people using ICT. Proposed future developments are: orientation towards web services - with building information models, business intelligence, personalization, AEC information retrieval, p2p workspaces and grids.
Der Sage nach wurde Europa, jene fremde Königstochter, vom Göttervater Zeus in der Verkleidung eines majestätischen Stiers vom fernen Phoenizien nach Kreta – wörtlich – „übertragen“, das heißt von hier nach dort getragen. So gesehen erzeugt Europa einen dritten Raum, einen Trenn- und/oder Bindestrich zwischen Orient und Okzident, als diasporadische Figur und auch als Kontinent. Die Logik eines solchen Strichs, der zugleich trennt und verbindet, findet eine kartographische Entsprechung im nullten Längengrad, der die ganze Welt in ein Einheit schaffendes Koordinatensystem „übersetzt“, mit Greenwich als Zentrum. Ein Äquivalent eines solchen fixen Ausgangspunktes findet sich in der perspektivischen Europa-Darstellung in Tiepolos Darstellung der Kontinente im Deckenfries des Treppenhauses der Fürstbischöflichen Residenz in Würzburg. In diesem architektonischen Gemälde bildet Europa das Frontispiz, das nur von einem privilegierten Standort auf dem ersten Treppenabsatz unverzerrt betrachtet werden kann. Gegenstand dieses Beitrags sind eben diese drei medienkulturellen Europa-Inszenierungen: 1.) eine Sage, 2.) das kartographische Element des Nullmeridians und 3.) Tiepolos Treppenhausgemälde, sie alle verstehe ich als medienkulturelle Übersetzungen Europas. Ziel dieses Beitrags ist es zu fragen, wie diese drei kulturellen Objekte in ihren jeweiligen medialen Modi am Europa-Begriff arbeiten. Dreh- und Angelpunkt ist dabei der Akt des Übersetzens, und zwar sowohl im Sinne einer Umschrift von einem medialen Modus in den anderen als auch als durchaus physisch zu verstehende Bewegung einer Migration zwischen Heimat und Fremde. Ergebnis dieser Betrachtungen ist ein Europa-Begriff, der nicht unproblematisch mit sich selbst identisch ist, sondern sich erst in der Bewegung des Übersetzens konstituiert, also im dritten Raum oder als Bindestrich zwischen den Kulturen.
Transport problems, as, for instance, the transport of sediment in hydraulic engineering and the transport of harmful substances through porous media, play an important role in many fields of civil engineering. Other examples include the dissipation of heat or sound as well as the simulation of traffic with macroscopic models. The contribution explains the analysis of the applicability of Voronoi-based finite volume methods for the approximation of solutions of transport problems. A special concern is the discretisation of the transport equation. Current limitations of the method as well as ideas for stabilisation are explained with examples.
The paper presents a general map-based approach to prototyping of products in virtual reality environments. Virtual prototyping of products is considered as a consistent simulation and visualization process mapping the source product model into its target visual representations. The approach enables to interrelate formally the product and visual information models with each other by defining mapping rules, to specify a prototyping scenario as a composition of map instances, and then to explore particular product models in virtual reality environments by interpreting the composed scenario. Having been realized, the proposed approach provides for the strongly formalized method and the common software framework to build virtual prototyping applications. As a result, the applications gain in expressiveness, reusability and reliability, as well as take on additional runtime flexibility...
Efforts to define standards for representing AEC/FM data have been fairly successful. However defining a standard reference process model has not met with the same success. Yet almost every conceptual modelling or software development project starts by defining the business processes to be supported and the related requirements to be satisfied. This paper describes a new process-centred methodology for user requirements capture developed in the ICCI project (IST-2001-33022). Its essence is in recognising user requirements and use cases in the context of the real construction process, identifying the actors and roles for each individual activity and associating these activities with information, communication and standardisation requirements on the basis of a formalised specification, named the Process Matrix. In the paper we outline the history of process matrix development, introduce the basic structure of the matrix and show how it can be further extended and refined. We present also a web-based software implementation of the developed approach, describe how it has been used in ICCI and outline further perspectives.
Current disaster management procedures rely primarily on heuristics which result in their strategies being very cautious and sub-optimum in terms of saving life, minimising damage and returning the building to its normal function. Also effective disaster management demands decentralized, dynamic, flexible, short term and across domain resource sharing, which is not well supported by existing distributing computing infrastructres. The paper proposes a conceptual framework for emergency management in the built environment, using Semantic Grid as an integrating platform for different technologies. The framework supports a distributed network of specialists in built environment, including structural engineers, building technologists, decision analysts etc. It brings together the necessary technology threads, including the Semantic Web (to provide a framework for shared definitions of terms, resources and relationships), Web Services (to provide dynamic discovery and integration) and Grid Computing (for enhanced computational power, high speed access, collaboration and security control) to support rapid formation of virtual teams for disaster management. The proposed framework also make an extensive use of modelling and simulation (both numerical and using visualisations), data mining (to find resources in legacy data sets) and visualisation. It also include a variety of hardware instruments with access to real time data. Furthermore the whole framework is centred on collaborative working by the virtual team. Although focus of this paper is on disaster management, many aspects of the discussed Grid and Visualisation technologies will be useful for any other forms of collaboration. Conclusions are drawn about the possible future impact on the built environment.
Pre-stressed structural elements are widely used in large-span structures. As a rule, they have higher stiffness characteristics. Pre-stressed rods can be applied as girders of different purpose, and as their separate parts, e.g. rods of trusses and frames. Among numerous ways of prestressing the compression of girders, trusses, and frames by tightenings from high-strength materials is under common application.
Analysis System for Bridge Test (Chinese name abbr.: QLJC) is an application software specially designed for bridge test to analyze the static and dynamic character of bridge structures, calculate efficiency ratio of load test, pick up the results of observation points and so on. In this paper, research content, system design, calculation theory, characteristics and practical application of QLJC is introduced in detail.
In this paper we present a computer aided method supporting co-operation between different project partners, such as architects and engineers, on the basis of strictly three-dimensional models. The center of our software architecture is a product model, described by the Industry Foundation Classes (IFC) of the International Alliance for Interoperability (IAI). From this a geometrical model is extracted and automatically transferred to a computational model serving as a basis for various simulation tasks. In this paper the focus is set on the advantage of the fully three-dimensional structural analysis performed by p-version of the finite element analysis. Other simulation methods are discussed in a separate contribution of this Volume (Treeck 2004). The validity of this approach will be shown in a complex example.
