A masonry building resting on laminated rubber bearing and subjected to ground acceleration due to Koyna earthquake is analyzed using three dimensional finite element method. The building and bearing is modeled using eight-noded isoparametric brick element with three degrees of freedom at each node. The response of building isolated at base is compared with the response of the building fixed at base. The response of isolated building is found to be less in comparison to the corresponding response without isolation system, implying that the isolation is quite effective in reducing response of the masonry structure. It is also found that the displacement at top and base of the isolated building are almost same at all time intervals. This indicates that the building moves rigidly during earthquake.
