Pushover Analysis of Low and Medium Rise RCC Frames With and Without Bracings for Regular & Irregular Buildings

Abstract

Recent earthquakes have caused severe damage to many concrete structures, so there is need for evaluating the seismic adequacy of structure. Steel Bracings was one of the most effective methods for RC frame building to improve the stiffness of the structure. This study is aimed at evaluating and comparing the response of G+5 and G+15 storey RC structures. The methodologies are applied to a regular and irregular plans (L, T and PLUS shaped plan) with and without considering the steel bracings. In the present study, we observe that base shear increases with the increases in mass and number of story of the building. L-Shaped irregular building plan shows a better performance compared to all other models.
