Effect of Various Concentric Bracing in Building

Abstract

Abstract While constructing a building the most important factor to be considered is its strength. Strength against different types of load that will be act on the structure after absolute construction. The most important type of load to be considered while construction is lateral load, cause not every structure can sustain lateral loads, especially high-rise structures build on earthquake prone areas. In order to resist lateral loads on such areas either the structure should have columns of higher section or we need to add shear wall or bracing to the structure. Bracing and shear wall provide lateral support to any structure. Bracing as well as shear wall takes the extra load of columns and beams during an earthquake which helps in load balancing. In this paper we have made a G+7 building and did earthquake analysis on STAAD.PRO software as per zone V. When earthquake load is applied to the structure without braces some of the columns an beams fail so in order to make the structure stable we applied braces (X and Diagonal) to the same structure and then compared the three models based on maximum storey displacement, maximum storey drift, bending moment, shear force and base shear.
