Review Paper on Inter Story Isolation System

Abstract

In higher seismic zones construction of high rise building with normal earthquake resistant design, it is necessary to provide their structural frame sufficient rigidity vertically and horizontally, make sure rigidity and strength in the plane. In base isolated building their upper structure experienced less seismic forces due to decoupling of superstructure to ground motion and is able to sustain concentration of rigidity and strength. Inter story isolation is evolved after the limitations of base isolation to meet the requirements of architectural, functional and cost consideration of structure. This system allows freedom for different structural planning of upper and lower level of isolation layer. In this paper seismic performance of buildings is measured using isolation at different levels. The different parameters like base shear, time period, story drift and story displacement are compared. Inter story isolation system also introduce high rise buildings by which the potential for new architectural planning and structural system is used for different purposes in building.
