Study of G + 20 Storey RC Framed Structure With Structural Steel Braces

Abstract

Earthquake is that the one of the main disaster better-known to mankind since a few years, there has been a considerable contribution from earthquake engineers for the protection of the structure. one amongst the alternatives to reduce the harm caused due to the earthquake is adopting steel bracings within the structure. These members is used within the building as a horizontal load resisting system to enhance the stiffness of the frame for seismic forces. this study is based on analysis of RC framed G+20 storey structure with steel braces using ETABS software. This study is conducted to know the behaviour of the various bracing system for different direction of the building. The building is situated in ZONE 5. The performance of building is studied in terms of Base shear, Base moment, Storey shear, Storey moment, Maximum displacement, Drift. The results of the analysis are compared and it was found that the seismal behavior of braced framed building is improved as compared to unbraced framed building. it had been also found that the various arrangements of bracing systems have great influence on seismic performance of the building. In this study considering the shape irregularity, mass irregularity.
