EFFECT OF DIFFERENT INFILL MATERIAL ON THE SEISMIC BEHAVIOR OF HIGH RISE BUILDING WITH SOFT STOREY

Abstract

Many urban multistory buildings in India today have open first storey as an unavoidable feature. This is primarily being adopted to accommodate parking or reception lobbies in the first stories. Also for offices or for any other purpose such as communication hall etc. The construction of reinforced concrete structures with infill wall is a common method of providing shelter to the ever increasing population, where there is seismic activity. In the present work, the effect of different infill materials on the seismic behavior of high rise building with soft stories is studied. For that, G+11 RCC model is selected. Different infill materials like siporex and Laminated glass are used. Different cases considering different location of soft stories are considered for the analysis. To study the effect of different infill material on high rise structure, linear dynamic analysis (Response spectrum analysis) in software ETABs is carried out. Seismic parameters like time period, base shear, storey displacement and storey drift are checked out
