Abstract

The objective of this report 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 Special Truss Moment Frames (STMFs) and comparison of their behavior. A 15 storey structure is considered in this study which is modelled in the ETabs software. The diagonal bracing system is considered for the damper configuration. The structures i.e., the bare frames and the retrofitted frames are subjected to linear time history analysis. Parameters such as lateral top displacement and energy dissipation behavior are studied for the bare and retrofitted frame and comparisons are drawn. Results indicate that the Fluid Viscous Damper significantly reduces the effects due to an earthquake and is an effective retrofit against seismic action for SMRFs. However, the FVDs only marginally improve the seismic performance of STMFs.
