On the lowest level we have geographical information systems (GIS) representing the outer layer of our planet as a 3D model. In the meantime these systems do not only give a geographical model but also present additional information like ownership, infrastructure and others that might be of interest for the construction business. In future these systems will serve as basis for virtual environments for planning and simulation of construction sites. In addition to this work is done on the integration of GIS systems with 3D city models in the area of urban planning and thus integration of different levels of detail. This article presents research work on the use of 3D models in construction on the next level of detail below the level of urban planning. The 3D city model is taken as basis for the 3D model of the construction site. In this virtual nD-world a contractor can organize and plan his resources, simulate different variants of construction processes and thus find out the most effective solution for the consideration of costs and time. On the basis of former researches the authors present a new approach for cost estimation and simulation using development technologies from game software.}, subject = {Produktmodell}, language = {en} } @article{BapirAbrahamczykWichtmannetal., author = {Bapir, Baban and Abrahamczyk, Lars and Wichtmann, Torsten and Prada-Sarmiento, Luis Felipe}, title = {Soil-structure interaction: A state-of-the-art review of modeling techniques and studies on seismic response of building structures}, series = {Frontiers in Built Environment}, volume = {2023}, journal = {Frontiers in Built Environment}, number = {Volume 9}, editor = {Ozturk, Baki}, publisher = {Frontiers Media}, address = {Lausanne}, doi = {10.3389/fbuil.2023.1120351}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20230206-49190}, pages = {1 -- 17}, abstract = {The present article aims to provide an overview of the consequences of dynamic soil-structure interaction (SSI) on building structures and the available modelling techniques to resolve SSI problems. The role of SSI has been traditionally considered beneficial to the response of structures. However, contemporary studies and evidence from past earthquakes showed detrimental effects of SSI in certain conditions. An overview of the related investigations and findings is presented and discussed in this article. Additionally, the main approaches to evaluate seismic soil-structure interaction problems with the commonly used modelling techniques and computational methods are highlighted. The strength, limitations, and application cases of each model are also discussed and compared. Moreover, the role of SSI in various design codes and global guidelines is summarized. Finally, the advancements and recent findings on the SSI effects on the seismic response of buildings with different structural systems and foundation types are presented. In addition, with the aim of helping new researchers to improve previous findings, the research gaps and future research tendencies in the SSI field are pointed out.}, subject = {Boden-Bauwerk-Wechselwirkung}, language = {en} }
