Base isolation (BI) is a method that has been applied around the world to safe the structures from the disaster effects of earthquake. The establishment of isolator at substructure considerably greater the mode period of building, it minimizes the prospect of vibration giving rise to quality seismic accomplishment of the building. The study is carried out to compare the performance (effectiveness) of base isolation in multi storied RC frame plan irregular and vertical irregular building. A RCC irregular building with 13(G+12) of plan irregular building with fixed and isolated base and 13(G+12) of Vertical irregular building with fixed and isolated base of dimension 33m X 42m and 39.5m height has been taken for seismic analysis. Base isolation effectiveness using Lead Rubber Bearing (LRB) is studied by Time history analysis (THA) method taking Bhuj earthquake data. The design of LRB is done manually. Four models are considered for analysis. The obtained results such as Time period, Base shear have been compared between building with fixed base and building with base isolation.
