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{KoenigTreyerSchmitt, author = {K{\"o}nig, Reinhard and Treyer, Lukas and Schmitt, Gerhard}, title = {Graphical smalltalk with my optimization system for urban planning tasks}, series = {31st eCAADe Conference - Volume 2}, booktitle = {31st eCAADe Conference - Volume 2}, publisher = {TU Delft}, address = {Delft, Netherlands}, doi = {10.25643/bauhaus-universitaet.2517}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20160121-25171}, pages = {195 -- 203}, abstract = {Based on the description of a conceptual framework for the representation of planning problems on various scales, we introduce an evolutionary design optimization system.

Amongst others, it can be used to improve the acoustic design of automobiles in an early development stage. Nowadays, the acoustics of automobiles plays a crucial role in the process of vehicle development. Because of the advanced demand of comfort and due to statutory rules the manufacturers are faced with the challenge of optimizing their car's sound emissions. The optimization includes not only the reduction of noises. Lately with the trend to hybrid and electric cars, it has been shown that vehicles can become too quiet. Thus, the prediction of structural and acoustic properties based on FE-simulations is becoming increasingly important before any experimental prototype is examined. With the state of the art, qualitative comparisons between different implementations are possible. However, an accurate and reliable quantitative prediction is still a challenge. One aspect in the context of increasing the prediction quality of acoustic (or general oscillating) problems - especially in power-trains of automobiles - is the more accurate implementation of damping in joint structures. While material damping occurs globally and homogenous in a structural system, the damping due to joints is a very local problem, since energy is especially dissipated in the vicinity of joints. This paper focusses on experimental and numerical studies performed on a single (extracted) screw connection. Starting with experimental studies that are used to identify the underlying physical model of the energy loss, the locally influencing parameters (e.g. the damping factor) should be identified. In contrast to similar research projects, the approach tends to a more local consideration within the joint interface. Tangential stiffness and energy loss within the interface are spatially distributed and interactions between the influencing parameters are regarded. As a result, the damping matrix is no longer proportional to mass or stiffness matrix, since it is composed of the global material damping and the local joint damping. With this new approach, the prediction quality can be increased, since the local distribution of the physical parameters within the joint interface corresponds much closer to the reality.}, subject = {Damping}, language = {en} } @inproceedings{HollermannMelzner, author = {Hollermann, Sebastian and Melzner, J{\"u}rgen}, title = {24.
