Maweihe Bridge is a skew bridge damaged in Wenchuan earthquake. The superstructure suffered great residual displacement. Abutments and side blocks were damaged due to the pounding. In order to make clear seismic response and failure mechanism of superstructure, dynamic analysis for the superstructure was conducted. The damage of abutment has been evaluated with the pounding stress as the damage degree is strongly related to it. Besides, it is found that velocity before poundings has a positive correlation with the pounding stress. |
