Paper Title:
Analysis of Linear Viscous Damper Parameters and Shock Absorption for Long-Span Cable-Stayed Bridge
  Abstract

The seismic behavior study of Fengdu Bridge will be conducted on a parameter of damping coefficient C of linear viscous dampers through linear dynamic time-history analysis. Simultaneously, the results are compared with the seismic response without viscous dampers. The parameter sensitivity study indicates that setting damper in longitudinal direction of bridge can reduce the relative displacement of key positions and the response of the bridge, the beneficial effect of the isolation in the longitudinal direction, but important amplification occurs in the vertical direction for relatively high frequency components. Moreover, the reference of application of linear viscous dampers will be provided for similar projects.
