Especially, viscous dampers are hydraulic devices widely used in structural engineering that dissipate mechanical energy by producing a damping force against the motion. The dampers can mitigate transversal and longitudinal or vertical displacement. It can be set up in different kinds of structures. This study is aimed at comparing the impact of various Fluid viscous damper parameters on the structures under the earthquake. To this aim, a seven-story steel frame structure retrofitted with fluid viscous dampers was considered for analyzing with a variety of parameters. The results showed that installing longitudinal nonlinear Fluid viscous damper can reduce the seismic response significantly, by selecting affordable damping parameters including stiffness, damping coefficient, and velocity exponent. The optimum damping parameters can be calculated accurately by analyzing structure with different damping parameters of nonlinear Fluid viscous damper.
