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} } @phdthesis{Nasser, author = {Nasser, Mourad}, title = {Quality Assessment of Dynamic Soil-Structure Interaction Models Using Energy Measures}, publisher = {Verlag der Bauhaus-Universit{\"a}t}, address = {Weimar}, isbn = {978-3-86068-494-8}, doi = {10.25643/bauhaus-universitaet.1854}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20130220-18542}, school = {Bauhaus-Universit{\"a}t Weimar}, pages = {132}, abstract = {In this research work, an energy approach is employed for assessing quality in dynamic soil-structure interaction (SSI) models, and energy measures are introduced and investigated as general indicators of structural response. Dynamic SSI models with various abstraction levels are then investigated according to different coupling scenarios for soil and structure models. The hypothesis of increasing model uncertainty with decreasing complexity is investigated and a mathematical framework is provided for the treatment of model uncertainty. This framework is applied to a case study involving alternative models for incorporating dynamic SSI effects. In the evaluation process, energy measures are used within the framework of the \textit{adjustment factor} approach in order to quantitatively assess the uncertainty associated with SSI models. Two primary types of uncertainty are considered, namely the uncertainty in the model framework and the uncertainty in the model input parameters. Investigations on model framework uncertainty show that the more complex three-dimensional FE model has the best quality of the models investigated, whereas the Wolf SSI model produces the lowest model uncertainty of the simpler models. The fixed-base model produces the highest estimated uncertainty and accordingly the worst quality of all models investigated. These results confirm the hypothesis of increasing model uncertainty with decreasing complexity only when the assessment is based on the ratio of structural hysteretic energy to input energy as a response indicator.}, subject = {Boden-Bauwerk-Wechselwirkung}, language = {en} } @misc{Schwedler2009, type = {Master Thesis}, author = {Schwedler, Michael}, title = {Untersuchungen adaptiver Modellanpassungen f{\"u}r Probleme dynamischer Bauwerks-Bodeninteraktion}, doi = {10.25643/bauhaus-universitaet.1405}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20091022-14896}, school = {Bauhaus-Universit{\"a}t Weimar}, year = {2009}, abstract = {Die Eigenschaften des Baugrunds k{\"o}nnen das dynamische Verhalten eines Bauwerks in erheblichem Maße beeinflussen.
