Reinforced concrete (RC) frame buildings with masonry infill walls have been widely constructed for commercial, industrial and multi storey residential uses in seismic regions. Masonry infill typically consists of bricks or concrete blocks constructed between beams and columns of a reinforced concrete frame. Masonry infill walls are widely used as partitions. They are considered as non- structural elements. RC frame building with open first storey is known as soft storey, a similar soft storey effect can also appear, at intermediate storey level if a storey used as a service storey. The soft storey located in the lower part of the high rise building especially the first storey is very undesirable as it attracts severely large seismic forces. At the same time, the soft storey located in the upper part of the high rise building does not significantly affect the performance compared to the performance of the fully infill frame. To study the effect of masonry infill and different soft storey level, 10 Models of R C framed building were analyzed with different types of shear walls when subjected to earthquake loading. The results of bare frame and other building models have been compared. Analysis is carried out by ETABS software. Storey displacement, time period, story drift and Storey acceleration is calculated by ESA, RSA and THA compared for all models. The results shows that the infill wall and shear walls gives the better performance in seismic analysis of building.
