OPTIMIZATION OF BRACING AND VISCOUS DAMPER AND COMPARISON OF FLUID VISCOUS DAMPER AND BRACING SYSTEM FOR STABILIZATION OF HIGH RISE BUILDING

Basically in case of tall building lateral loads i.e. earthquake and wind always governing the design. So, to counteract these loads, a proper lateral load resisting system should be used to fulfill design and serviceability criteria. Lateral bracing and fluid viscous damper are among those system which can be used to fulfill strength and latera stiffness criteria. In this paper a 20 story reinforced concrete building has been modeled in standard package ETABS 2016 for the purpose of study. Total of 6 models have been made, bare frame, bracing with its type and fluid viscous damper. Also equivalent static and linear response spectrum analysis have been performed to capture accurate response of structure. For seismic efficiency base shear, time period and lateral deflection of each model have found and compared with each other
