Abstract

Base Isolation technique is used to decouple the base from its superstructure during the ground motions caused by earthquake. The present study is done on a G+4 storey building, considering three models where the first model indicates the bare frame structure, second model indicates the with infill structure which is modelled as equivalent diagonal strut and the third model indicates the base isolated structure using friction pendulum bearing. The main objective is to study the dynamic response of with infill and without infill structure and carrying design of FPS for the maximum response of structure such as lateral displacement and storey drift. The dynamic analysis of with infill and without infill structure indicated that the structure is stiffer with infill effect and structural response also get reduces. The base isolated structure reduces the inter storey drift and lateral load effects on the structure.
