Abstract

Shear wall and Steel bracing systems are most widely used in medium to high rise buildings to provide stiffness, strength and energy dissipation required to resist lateral load imposed by earthquakes and wind. In the past shear wall and steel bracing have been proved as most feasible solution for seismic retrofitting or strengthening of buildings. The newly adopted performance evaluation methodology and capacity design principles are examples of these important advancements in seismic engineering. Many existing RC buildings need to retrofit to overcome weaknesses to resist seismic loads. Therefore, there is an essential need to upgrade the seismic performance of existing RC buildings so that they can meet the requirements of the new performance-based seismic design techniques. In this paper, seismic performance of RC building rehabilitated with shear wall and concentrated steel bracing. An earthquake load is calculated and applied on nine stories building located in zone III. A comparison has been made between the effectiveness of different types of steel bracings with concrete shear wall at different locations of the building. The performance of the building is evaluated in terms of story drifts, lateral displacements, bending moments and base shear.
