Abstract

This paper investigates the seismic behavior of multi storey building using damping devices strategically located within the lateral load resisting elements (shear wall). The study concentrates on a retrofitting strategy with passive energy dissipation device known as Fluid Viscous Damper (FVD) which can be used to retrofit existing buildings to ensure seismic safety by fitting damping devices which can transform a wall panel into a damping element. Nine, Eighteen and Twenty seven storey shear wall structures with three cut out sections provided at different storey levels were analyzed using software SAP2000 to obtain its seismic behavior without and with linear FVD retrofitting so as to obtain an optimum damper location and results were compared with respect to peak roof deflection and roof acceleration.Time history analysis is used in the study and results indicate that dampers provided at lower levels as well as at the places of maximum interstorey drifts in shear wall showed reduction in seismic response.
