Base isolation is a technique is used to protect the building structure from earthquake motion. The installation of isolator in building at base level significantly increases the fundamental 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. Base isolation is a technology to protect different structures like building, water tanks, bridges, airport terminals and nuclear power plants etc. from earthquake motions. The study aims to compare the effectiveness of base isolation in plan irregularity and vertical irregularity building. In the present study a G+15 building is considered and response spectrum analysis is carried out using ETABS software. The study was made with use of IS: 1893(Part 1) and Lead Rubber Bearing (LRB) is used for the base isolation system. The response of the buildings in terms of time period, storey shear, storey drift and storey acceleration are compared between plan irregular and vertical irregular structures.
