In Structural analysis, masonry infills are commonly considered to be non-structural elements. However the response of reinforced concrete buildings to earthquake loads can be substantially be affected by the influence of infill walls. The increase in overall stiffness and strength is the positive effect of the presence of infill walls. Scope of work is to compare the seismic response of the reinforced concrete Fixed and Base isolated buildings and to compare the influence of the masonry infill walls in Fixed and Base isolated buildings. In this work, masonry infill walls are modeled using the equivalent diagonal strut concept in order to assess their involvement in seismic resistance of reinforced concrete buildings. The influence of the masonry on global response of RC frame is analyzed using dynamic linear analysis. As a base isolated system Lead Rubber bearing isolator is used. The parametric study is carried out for G+5 and G+7 storey buildings. The Response spectrum analysis is carried out using ETABS® software.At the end building response parameters are compared.
