Abstract: The base isolation is a technique which decouples the structure from its foundation[1], which reduces the impact of the vibration caused by the earthquake. It is most used system for the reduction of the damage caused by vibration of the structure. In the current study, G+4 Asymmetric building is considered for seismic analysis. Response Spectrum Analysis is performed on the Etabs software[2]. The study is performed by using the Lead Rubber Bearing (LRB) and Fixed Base and the results are compared in terms of time period, displacement and base shear[3]. The LRB is designed by using International Building Code (2005) and seismic analysis is done by IS1893:2016. It shows that the time period of the structure increases in the base isolated structure[3]. Base shear is reduced by 57% in LRB than fixed base and deflection of the structure increases.
