A large proportion of world's population lives in regions of seismic hazards, at risk from earthquakes of varying severity and frequency of occurrence. Earthquake causes significant loss of life and damage of property every year. So, to mitigate the effect of earthquake on building the base isolation technique one of the best solutions. The concept of protecting a building from the damaging effects of an earthquake by introducing some type of support that isolates it from the shaking ground is an attractive one and many mechanisms to achieve here results have been developed. In present research work modeling is done using SAP software, model consists of 8 storeyed ordinary moment resisting frame. 1940 El Centro earthquake 0.319g data is considered for Time history analysis. By conducting Time history analysis floor displacement and roof displacement response curves of the isolated structures with fixed base are plotted which indicates that the displacement for isolated structures is more at base in comparison with fixed base and it reduces as the storey height increases. Reduction in acceleration and velocity response compared to fixed base structure.
