Abstract

Base isolation technique is introduced to improve the performance of the building. The base isolation technique is used to decouple the base from its superstructure during the ground motion caused by earthquakes. The installation of isolator in a building at a base level significantly increases the time period of the structure which means it reduces the possibility of resonance of the structure giving rise to better seismic performance of the building. The main aim of this paper is the use of Friction Pendulum Bearing (FPB) and High- Density Rubber Bearing (HDRB) as an isolation device and then to compare various parameters between fixed base condition and base-isolated condition. The modeling procedure for  both  building has been done using ETABS 2017 software for a regular (G+5) storied OMRF building. Linear analysis using Time History Analysis (THA) for the records of Elcentro earthquake (1940) and Response spectrum analysis (RSA) has been carried out
