Description

Soil-structure interaction (SSI) is for sure one of the most neglected effects in seismic structural design practice. However, many researchers showed that it might notably affect seismic performance results. In fact, the state-of-the-art seismic codes are encouraging including SSI for structures with considerable p-Δ effects and mid to high-rise buildings. In the current research, seismic soil-structure interaction analysis is made for a selected high-rise reinforced concrete building with several different SSI techniques (models). In order to quantify the effect of SSI on the overall response of the selected structure, the global seismic response within a frame of force-displacement relationship for different earthquake intensities, different SSI mathematical models and different soil categories is presented. Comparing the outcome of the performed analysis it was observed that the structural performance was affected significantly by the foundation system and contributes considerably to the overall structural performance of the selected high-rise structure in selected soil conditions. As the results indicate, more code-based recommendations are required for the improvement of the SSI structural seismic design, especially in soft soil cases, where the soil-structure interaction might significantly affect the seismic response of buildings.
