Such specialist systems must take into account currently available technology, such as networked working patterns, object-orientation, building and product models as well as the working method of the planner. The paper describes a plausibility instrument for the formulation of colour scheme proposals for building interiors and elevations. With the help of intuitively usable light simulations, colour, material and spatial concepts can be assessed realistically. The software prototype "Coloured Architecture" is conceived as a professional extension to conventional design tools for the modelling of buildings. As such it can be used by the architect in the earliest design phases of the planning process as well as for colour implementation on location.}, subject = {CAD / Architektur}, language = {en} } @inproceedings{TonnWolkowiczThurow2004, author = {Tonn, Christian and Wolkowicz, Christian and Thurow, Torsten}, title = {Plausibility in Architectural Design - DOMEdesign - Software Support for the formal shaping and architect-oriented design of shell structures}, doi = {10.25643/bauhaus-universitaet.181}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20111215-1812}, year = {2004}, abstract = {Complex gridshell structures used in architecturally ambitious constructions remain as appealing as ever in the public realm. This paper describes the theory and approach behind the software realisation of a tool which helps in finding the affine self-weight geometry of gridshell structures. The software tool DOMEdesign supports the formal design process of lattice and grid shell structures based upon the laws of physics. The computer-aided simulation of suspension models is used to derive structurally favourable forms for domes and arches subject to compression load, based upon the input of simple architectonic parameters. Irregular plans, three-dimensional topography, a choice different kinds of shell lattice structures and the desired height of the dome are examples of design parameters which can be used to modify the architectural design. The provision of data export formats for structural dimensioning and visualisation software enables engineers and planners to use the data in future planning and to communicate the design to the client.}, subject = {Architektur}, language = {en} } @inproceedings{Kapellmann2004, author = {Kapellmann, Klaus D.}, title = {Planungshaftung bei Vertr{\"a}gen auf der Basis funktionaler oder teilfunktionaler Leistungsbeschreibung}, doi = {10.25643/bauhaus-universitaet.718}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20111215-7188}, year = {2004}, abstract = {Funktionale Leistungsbeschreibung, das auf die Planung anzuwendende Recht, vertragliche Zuteilung der Planungspflicht, fehlerhafte Auftraggeberplanung, Probleme beim Construction Management}, subject = {Baubetriebslehre}, language = {de} } @article{KangMiranda2004, author = {Kang, Shihchung and Miranda, Eduardo}, title = {Physics Based Model for Simulating the Dynamics of Tower Cranes}, doi = {10.25643/bauhaus-universitaet.240}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20111215-2409}, year = {2004}, abstract = {The goal of the research is to increase the understanding of dynamic behaviors during the crane operation, and develops computer-aided methods to improve the training of crane operators. There are approximately 125,000 cranes in operation today in the construction industry, responsible for major portion of erection activities. Unfortunately, many accidents occur every year in the U.S. and other countries related to the operation of cranes in construction sites. For example on November 28, 1989 a tower crane collapse during the construction of a building in San Francisco killing four construction workers, one civilian and injuring 28. 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)...}, subject = {Produktmodell}, language = {en} } @article{GaoWuRen2004, author = {Gao, Zuoren and Wu, Weiyu and Ren, Aizhu}, title = {Physically Based Modeling and Multi-Physical Simulation System for Wood Structure Fire Performance}, doi = {10.25643/bauhaus-universitaet.238}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20111215-2381}, year = {2004}, 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.
