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.}, subject = {Modeling}, language = {en} } @inproceedings{BargstaedtAilland2011, author = {Bargst{\"a}dt, Hans-Joachim and Ailland, Karin}, title = {CONVR 2011 : Proceedings of the 11th International Conference on Construction Applications of Virtual Reality}, isbn = {978-3-86068-458-0}, doi = {10.25643/bauhaus-universitaet.1468}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20111102-15603}, year = {2011}, abstract = {Proceedings of the 11th International Conference on Construction Applications of Virtual Reality}, subject = {Plant Simulation }, language = {en} } @inproceedings{FahrigNachtweyGellert2004, author = {Fahrig, Torsten and Nachtwey, Bj{\"o}rn and Gellert, Sebastian}, title = {A Product Model based Approach to Interactive CAE Design Optimization}, doi = {10.25643/bauhaus-universitaet.190}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20111215-1901}, year = {2004}, abstract = {We present a software prototype for fluid flow problems in civil engineering, which combines essential features of Computational Steering approaches with efficient methods for model transfer and high performance computing.

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.

Simulationsergebnisse zur sommerlichen {\"U}berhitzung von nat{\"u}rlich bel{\"u}fteten Geb{\"a}uden in Deutschland und Großbritannien zeigen jedoch f{\"u}r einige Wetterstationen weniger {\"U}berhitzung f{\"u}r Simulationen mit dem sommer-fokussierten Referenzjahr als f{\"u}r solche mit dem entsprechenden Testreferenzjahr (TRY) f{\"u}r den gleichen Ort. Dies gilt insbesondere dann, wenn einzelne Monate miteinander verglichen werden. Neben der Wahl eines kompletten Halbjahres, das sowohl extrem warme als auch vergleichsweise k{\"u}hle Monate beinhalten kann, liegt dies vor allem begr{\"u}ndet in der fehlenden Ber{\"u}cksichtigung der Solarstrahlung bei der Auswahl eines warmen Referenzjahres, die jedoch eine wichtige Rolle f{\"u}r sommerliche {\"U}berhitzungserscheinungen in Geb{\"a}uden spielt. Eine verl{\"a}ssliche, allgemein anerkannte Methode zur Erstellung von sommer-fokussierten Referenzjahren erscheint daher auch im Hinblick auf die rechtlichen Rahmenbedingungen in der Europ{\"a}ischen Union, die Strategien zur nat{\"u}rlichen Bel{\"u}ftung von Neubauten und Sanierungen beg{\"u}nstigen, erforderlich. Diese Arbeit pr{\"a}sentiert einen Ansatz zur Erstellung eines Sommerreferenzjahres (Summer Reference Year - SRY) aus dem TRY eines gegebenen Ortes und langj{\"a}hrigen Klimadaten. Die existierenden TRY-Daten werden hierbei skaliert, um den Bedingungen f{\"u}r Trockentemperatur und Solarstrahlung von nah-extremen Kandidatenjahren zu entsprechen, die separat {\"u}ber einen statistischen Ansatz ausgew{\"a}hlt werden. Anschließend werden Feuchttemperatur, Windgeschwindigkeit und Luftdruck des TRY durch lineare Korrelationen mit der Trockentemperatur angepasst, um die entsprechenden SRY-Daten zu erhalten. Der Vorteil dieser Methode liegt darin, dass das grundlegende Wettermuster des TRY erhalten bleibt und somit eine klare Relation zwischen SRY und TRY besteht, die eine Vergleichbarkeit von Simulationsergebnissen gew{\"a}hrleistet. {\"U}ber vergleichende Geb{\"a}udesimulationen mit dem zugrundeliegenden TRY und langj{\"a}hrigen Klimadatens{\"a}tzen kann nachgewiesen werden, dass sich das SRY zur Ermittlung sommerlicher {\"U}berhitzungserscheinungen in nat{\"u}rlich bel{\"u}fteten Geb{\"a}uden eignet. Weiterhin kann gezeigt werden, dass das SRY im Gegensatz zur direkten Nutzung eines Kandidatenjahres f{\"u}r einen nah-extremen Sommer die M{\"o}glichkeit eines monatsscharfen Vergleichs mit dem TRY erlaubt und frei von wenig repr{\"a}sentativen Besonderheiten ist, die in den entsprechenden Kandidatenjahren vorhanden sein k{\"o}nnen.}, subject = {Bauphysik}, language = {de} } @inproceedings{Kath2005, author = {Kath, Thilo}, title = {Sicher arbeiten mit Kr{\"a}nen durch Simulation und Visualisierung}, doi = {10.25643/bauhaus-universitaet.690}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20111215-6901}, year = {2005}, abstract = {Bestimmungen und Anforderungen an den Entwurf von Baustelleneinrichtungen (BE), Kraneinsatzplan als Bestandteil der BE, planungstechnische Aspekte, Untersuchung von CAD-Anwendungen f{\"u}r die Planung von Baustelleneinrichtungen, Entwicklung eines Kraneinsatzplaners, Sicherheitsaspekte bei der Planung von Baukraneins{\"a}tzen.

By replicating the growth or shrinkage of a city using historical maps depicting different time states, we can obtain momentary snapshots of the dynamic mechanisms of the city. An examination of how these snapshots change over the course of time and a comparison of the different static time states reveals the various interdependencies of population density, technical infrastructure and the availability of public transport facilities. Urban infrastructure and facilities are not distributed evenly across the city - rather they are subject to different patterns and speeds of spread over the course of time and follow different spatial and temporal regularities. The reasons and underlying processes that cause the transition from one state to another result from the same recurring but varyingly pronounced hidden forces and their complex interactions. Such forces encompass a variety of economic, social, cultural and ecological conditions whose respective weighting defines the development of a city in general. Urban development is, however, not solely a product of the different spatial distribution of economic, legal or social indicators but also of the distribution of infrastructure. But to what extent is the development of a city affected by the changing provision of infrastructure?

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.}, subject = {Baubetrieb}, language = {en} }
