Abstract: This paper is concerned with study of effect of infill walls on R.C framed structures. Reinforced concrete (RC) frame buildings with masonry infill walls have been widely constructed for commercial, industrial and multi storey residential building. Masonry infill walls, typically consists of bricks or concrete blocks constructed between beams and columns of a reinforced concrete frame. The purpose of this analysis is to study the behavior of RC structure especially when it is subjected to seismic loads. A comparative study is carried out with RC building using Equivalent Lateral Force method, Response Spectrum analysis and time history analysis. In the present study, G+14 R.C.C framed building models is considered and analysed using ETABS software. Equivalent static method and Response Spectrum method of analysis has been used on the building, for analysis as per IS 1893:2002 and results obtained from the analysis are compared. Model analysis is carried out for medium soil and resulting displacement and drift are obtained. Time history analysis is done for all models. Results obtained are compared. The results of these models shows that, infill wall decreases the displacement of the structure and infill wall with opening has higher displacement when compared to infill wall without opening. Drift increases where infill is not provided.
