Abstract:

The seismic response time-history of a continuous girder bridge with viscoelastic damper is analyzed. The effect of vibration mitigation of the damper in bridge and the influence of the damper parameters to the absorption effect are discussed. The result shows that the bridge with viscoelastic damper can minimize seismic response, and the damper parameter should be optimized in order to get nicer effect.
