Fluid viscous dampers (FVDs) are well suited to vibration control of highway bridges subjected to seismic excitations. However, the parametric selection of dampers for a real project is lacking a simple and quick estimation method. The research of seismic behavior of a 3-pylon cable-stayed bridge with fluid viscous dampers has been conducted to investigate two parameters (damping coefficient C and damping exponent α) of the FVDs through nonlinear, dynamic, time-history analysis. The parameter sensitivity study indicates that setting dampers in the bridge longitudinal direction can reduce the response of the bridge. Design proposals are suggested following the results of the parametric study, as well.
