Abstract

The past major earthquake demonstrated that strength alone would not be protecting the structure during earthquakes. Base isolation is an advanced technology used to protect the structure from the damaging effect of earthquake. The objective of base isolation is to decouple the structure from the damaging component of the earthquake. Soil flexibility has a great effect on the dynamic response of structure. Soil-structure interaction modifies the system responses and there by alter the structural response. Soil structure interaction has been extended to the field of base isolation and gaining interest of the researcher in last few years. This paper introduces the concept of soil interaction and base isolation with the development in the field, and presents a review on some of the leading development in the field of soil structure interaction on base isolated buildings. Numerical study has been presented to study the effectiveness of the FEM and convectional method of modeling in soil structure interaction of base isolated structure.
