【Abstract】 This paper makes a detailed analysis to the damping coefficient and speed index of viscous damper for Anqing Yangtze River Bridge by the non-linear time history analysis method,and discusses the influences of different parameters of damper on seismic response of structures.The results demonstrate that the viscous damper can obviously reduce the seismic response of bridge structures.Finally,this paper gives a proposal for the parameters of viscous damper for reference.更多还原
