The Anti-Seismic Performance of the Viscous Damper and E Shaped Steel Bearing

Abstract:

To study the anti-seismic performance of the viscous damper and the E shaped steel bearing on the continuous girder bridge, two models of the Taibai bridge located in Xi’an are analyzed by the nonlinear time-history method and the Midas/Civil software, considering the interaction between pile and soil. The related data are obtained through the two computational models. The results show that the bending moments and shear forces of the bottom of the fixed pier are reduced and it is effective to reduce the displacements of the top of the fixed pier and the end of the girder. And, the viscous damper and the E shaped steel bearing form the large hysteresis loops, dissipate the earthquake energy and reduce the earthquake response of the bridge.
