Short Review on Soil-Structure Implementation in Base Isolated Structures

Abstract

Abstract Structural control is a subject that has been gaining interest for almost the last forty years. However, soil-structure interaction (SSI) implementation in control studies is relatively new, but it has attracted many researchers’ attention for both theoretical and experimental research. Besides structural control SSI is an important topic which should be studied more. SSI was not considered during the design stages of different structures, which led in the unexpected results after the earthquakes. In this paper the studies considering SSI in base isolated structures are reviewed. From the structural and earthquake engineering point of view, many studies considered near or far fault earthquakes and used scaled mathematical models for numerical examples. Most of the research is based on existing results of the earthquakes and real building damages. On the other hand, there are some researchers who designed scaled structures to perform experimental works under artificial earthquake excitation in order to investigate the seismic performance of the structures. This study aims to demonstrate the conclusion and numerical examples obtained from base isolation studies considering SSI. With regards to the short review, it can be mentioned that SSI affects the structure and the behaviour of the base isolation. Considering SSI in base isolation research might increase the authenticity of the corresponding study and might result in more realistic results than fixed base structural analysis.
