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-Universität 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.
Bestimmungen und Anforderungen an den Entwurf von Baustelleneinrichtungen (BE), Kraneinsatzplan als Bestandteil der BE, planungstechnische Aspekte, Untersuchung von CAD-Anwendungen für die Planung von Baustelleneinrichtungen, Entwicklung eines Kraneinsatzplaners, Sicherheitsaspekte bei der Planung von Baukraneinsätzen. Es zeigte sich, dass gerade die Forderung der Betrachtung kausaler und räumlicher Abhängigkeiten mit den in der Praxis angewandten Planungswerkzeugen nicht oder nur eingeschränkt realisierbar ist. Mit dem Programm >EasyCrane TK< wird eine Möglichkeit aufgezeigt, die Erstellung von Kraneinsatzplänen effizienter und für die Umsetzung auf der Baustelle sicherer zu gestalten.
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 main components of the system are described: - The modeler with a focus on the data management of the product model - The pre-processing and the post-processing toolkit - The simulation kernel based on the Lattice Boltzmann method - The required hardware for real-time computing
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.
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.
A simulation system has been developed as a computer aided design tool to evaluate the effect of proposed design on the thermal environment during the designing process. This system calculates outdoor surface temperatures in order to evaluate the thermal impact of a design factor in outdoor space. In this study, the previous heat balance simulation system was improved to predict the surface temperature of a proposed design using 3D-CAD. This system is able to input the complicated outdoor spatial forms efficiently and also to evaluate the surface temperature distribution from any viewpoint.
