Abstract

A common cause for collapse of Multistoried RCC building due to earthquake is occurrence of soft storey in ground floor due to presence of infill wall in upper story leading to stiffness irregularity between floors and increased shear force in ground floor columns. In current design practices stiffness and energy absorption system are combined in single system. Various soft storey strengthening techniques like use of steel bracings, dampers, column jacketing etc. have been studied in past. This paper focuses on studying the effect of special type of bracing as Crescent shaped steel bracing in ground soft storey of a G+12 storied RCC building located in Zone III, India. Response spectrum analysis is carried out for the structure using ETABS2015 software and results are computed based on storey displacement, drift, stiffness, time period and base shear.
