A large proportion of world’s population lives under higher seismic risk region so there is a need of construction technologies which resist higher seismic forces and Base-isolation is such type of technology Base isolation system for building is introduced to decouple/isolate the superstructure of the building from potentially damaging due to earthquake motion. The main goal of this research is to find out of base isolation is to reduce the drift of the building. The present study is an attempt to understand the effectiveness of Base-isolation on different storey height for aspect ratio (HB/LB) of building. Four different height of building G+5 to G+20 every five incremental story has been taken. The effectiveness has been checked for aspect ratio (HB/LB) is 1 (HB=LB) . To avoid flexural behavior symmetrical building with Base isolation at the below the ground level in building was taken. The Building dimensions were restricted by Building aspect ratio (HB/LB). The response spectrum analysis of building without Base-isolation and with Base-isolation in Lead Rubber Bearing was carried out using ETABS® software. At the end, building response parameter Storey Drift was compared.
