Research on Fluid Viscous Damper Parameters of Cable-Stayed Bridge in Northwest China by Xiongjun He, Yongchao Yang, Xiang Xiao, Yulin Deng

“…The results indicate that seismic response in key positions of the cable-stayed bridge can be reduced by installing longitudinal nonlinear FVD between the towers and girders if choosing reasonable damping parameters C and ξ. The optimal damping parameters can be calculated accurately by the proposed method of optimizing damping parameters of nonlinear FVD, and the constitutive relation test verifies the correctness of the optimization analysis method. …”
