SEISMIC BEHAVIOR OF MULTISTOREYED FRAME BUILDING WITH FLUID VISCOUS DAMPER

Abstract

Multi-storeyed buildings are the most economical solution to accommodate the large amount of population in a small space. But as height of building increases lateral forces becomes a major concern to the designer. Providing fluid viscous dampers in multi-storeyed building is one of the effective methods to reduce the response of the structure, when subjected to lateral forces. Fluid viscous damper increases damping capacity of building structure and helps to dissipate energy when subjected to ground motion. In the present study, a building in which fluid viscous dampers are installed in two different positions are analysed for lateral forces when subjected to ground motion in ETABS 2016 by response spectrum method and their responses such as storey displacement and storey drift compared with the model without fluid viscous damper. A fluid viscous damper helps to reduce storey displacement and storey drift significantly.
