Abstract

In this study the effect of soil-structure interaction on seismic performance is investigated considering a 15 story building incorporating base and mid-story seismic isolation. The cases that are taken into account are; fixed base model, base isolated model and base and mid-story isolated model. All three models are analyzed by excluding and including soil-structure interaction. Three different earthquakes are used for the time-history analysis. It is concluded that the seismic performance is enhanced by the implementation of base and mid-story isolation to the structure. In addition, it is observed that soil-structure interaction had a small effect on seismic performance of the structure depending on the base soil type.
