Abstract

The steel braced frame is one of the structural systems used to resist earthquake loads in multistoried buildings. Many existing reinforced concrete buildings need a retrofit to overcome deficiencies to resist seismic loads. The use of steel bracing systems for strengthening or retrofitting seismically inadequate reinforced concrete frames is a viable solution for enhancing earthquake resistance. Steel bracing is economical, easy to erect, occupies less space and has the flexibility to design for meeting the required strength and stiffness. In the present study, the seismic study of conventional x brace, zipper brace, and SBS in RCC structures using ETABS software is investigated. The bracing is provided at each corner. a g+6, g+12 and g+18 story with 6 bay in an x-direction and 3 bay in the y-direction is analyzed using ETABS. The effectiveness of various types of steel bracing is examined. The effect of the distribution of the steel bracing along the height of the RCC structure on the seismic performance of the rehabilitated building is studied. Provision of conventional x braced, zipper braced and SBS is provided in each story. The percentage reduction in lateral displacement is found out. It is found that the SBS of steel bracing significantly contributes to the reduction in displacement and story shear compared to conventional x bracings.
