Abstract

The objective of this paper is to investigate the effect of Fluid Viscous Dampers (FVDs) on the seismic response of a structure. This study includes seismic retrofit of FVDs to Special Moment Resisting Frames (SMRFs) and comparison of its behavior. A 15 storey structure was considered in this study which was modelled in the ETabs software. The diagonal bracing system was considered for the damper configuration. The structures i.e., the bare frame and the retrofitted frame were subjected to response spectrum analysis. Various parameters such as storey displacements, storey drifts and storey shears were compared for the bare frame and the retrofitted frame. Results indicated that the Fluid Viscous Damper significantly reduces the effects due to an earthquake and is an effective retrofit tool against seismic actions
