Comparison of response of the structures against seismic force

Abstract

The study of this paper is to assess the seismic vulnerability and response of regular and irregular shaped multi-storey building of same floor area 825 square meters. The regular building of rectangle shape is considered and irregular building of L shape structure is considered for the analysis. 11 storeyed regular (rectangular) shaped and irregular (L-shape) shaped buildings have been modeled using computer program ETABS 2016. Firstly the both rectangle and L shape buildings are analyzed with bare frame without any infill walls, later the rectangle and L shape buildings are analyzed by providing external infill walls around the plan of 10m×15m respectively. The analysis is done by Response spectrum method according to IS 1893(part 1): 2002. Comparative study on the maximum storey displacement, maximum storey drift and time periods of L and rectangular shaped building due to dynamic response spectrum has been explored. . From the results it is inferred that building with severe irregularity produces more deformation than regular building.
