There has been a great loss of life and property due to the occurrence of earthquakes in the past. The poorly constructed buildings are likely to collapse during earthquakes. There is a need to reduce the seismic demand on these buildings so that they can perform better during future earthquakes. This need can be fulfilled using the concept of base isolation. In seismic base isolation, the superstructure is decoupled from the potentially damaging ground motion. In order to predict the response of the structure during earthquake, accurate evaluation of structural properties and precise modelling of the isolation devices has to be done. A case study has been taken up to compare the response of base isolated building with that of a conventionally designed earthquake resistant building. The finite element software SAP2000 has been used for modelling and analysis. Non-linear static pushover analysis and non-linear time history analysis have been performed to study the response of base isolated building as well as fixed base conventionally designed building.
