Damage Investigation of Girder Bridges under Wenchuan Earthquake and Seismic Design Recommendations
The investigation of the affected girder bridges in the state route 213 after Wenchuan earthquake shows that the typical damages are fall of girder, unseat, shear key failure, and damage of expansion joint due to the slide induced large relative displacement between the bottom of the main girder and the top of the laminated-rubber bearing. This slide, however, can actually act as isolation for the substructure, as a result, the piers and fundaments of bridges in the state route 213 are subjected to minimum damage except for Bai Hua Bridge. Followed the discussion, corresponding seismic design recommendations are then presented.
