TY - CHAP ED - Abrahamczyk, Lars ED - Schwarz, Jochen ED - Werner, Frank T1 - Model Validation and Simulation N2 - 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.

This system is exemplified by means of the generation of street networks with locally defined properties for centrality. We show three different scenarios for planning requirements and evaluate the resulting structures with respect to the requirements of our framework. Finally the potentials and challenges of the presented approach are discussed in detail.

Workshop zu Handlungsansätzen hochschulinterner Flächensteuerung N2 - Die Publikation dokumentiert die Beiträge des Workshops „Flächenmanagement in Hochschulen“ der Bauhaus-Universität Weimar, Professur Betriebswirtschaftslehre im Bauwesen, vom 19.11.2012. Insbesondere für Akteure aus Lehre, Forschung, Hochschulverwaltung, Bau- und Liegenschaftsverwaltungen sowie Politik bieten die wiedergegebenen Vorträge theoretische und praktische Anregungen für das Vorgehen bei der Steuerung hochschulinterner Flächen. Dokumentiert werden unterschiedliche Modi zur Steuerung der Flächenressourcen. Ziel ist es dabei, die liegenschaftspolitischen Rahmenbedingungen aufzuzeigen, von denen das Flächenmanagement abhängig ist. Mit der Auswertung einer deutschlandweiten Hochschulbefragung zum Flächenmanagement wird der Status quo hochschulinterner Flächensteuerung nachgezeichnet. Es wird zuerst ein Überblick gegeben, welche Ansätze zur Optimierung der Flächen-steuerung von Hochschulen möglich sind. Hochschulvertreter von zwei staatlichen und einer privaten Hochschule stellten praktizierte Handlungsansätze für einen ressourcenschonenden Umgang mit Flächen vor und arbeiteten die aus ihrer Sicht Erfolg versprechenden Steuerungsaspekte heraus. Zusätzliche Diskussionsimpulse für die Flächensteuerung an Hochschulen bieten die Dokumentationen von Praxisbeispielen aus anderen Bereichen. Es werden das Vorgehen bei der Flächensteuerung eines Chemie- und Pharmakonzerns mit umfangreichen eigenen Forschungsaktivitäten sowie Flächenoptimierungsmaßnahmen bei Büroflächen der öffentlichen Verwaltung vorgestellt.

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.
