The design of high rise building should involve the good lateral load resisting system along with the vertical loads acting on the building as wind load will govern in high rise buildings. This paper is presented to show the variation of shear force, axial force, bending moment and deflection that would be developed in high rise buildings with different bracing systems at different locations subjected to wind and seismic loading. For this purpose the G+20 storied reinforced concrete building model is used with a constant configuration and with different bracing system such as diagonal bracing, X-bracing, V-bracing, chevron bracing at different locations. A structural analysis is performed by using software STAAD-Pro V8i and different parameters are studied and compared. The sections of such as beams, columns, bracings sare as per IS 800:2007 based on the limit state parameters. Based on the study it can be concluded that along with the type of bracing the locations of bracings is also of great importance in resisting lateral load.
