Paper Title:
Influence of Soil-Pile Interaction on Seismic Mitigation Effectiveness with FPB for Curved Girder Bridge
  Abstract

The seismic response of curved girder bridge is more complex because of its irregular plane shape. Friction pendulum bearing (FPB) has a positive effect on structural seismic response. The seismic response mitigation effectiveness of FPB to curved girder bridge with soil-pile interaction considered is needed to research. The three-dimensional calculation model of a curved continuous girder bridge is established, and FPB are added at the positions of sliding bearings with soil-pile interaction. The influence of soil-pile interaction on seismic response mitigation effectiveness of FPB is computed and analyzed under three-dimensional ground motion action. The results show that the seismic response mitigation effectiveness of FPB is quite obvious with or without soil-pile interaction considered. Furthermore, seismic response mitigation effectiveness of FPB increases for the internal force of piers after soil-pile interaction considered. FPB has great and positive mitigation effectiveness on the seismic longitudinal displacement of the main girder of curved girder bridge, but with soil-pile interaction considered the mitigation effectiveness decreases a bit.
