Abstract
Maweihe Bridge is a skew bridge damaged in Wenchuan earthquake on May 12th, 2008. Serious damage has been found at abutment and side blocks. Pounding induced damage has been discussed. In order to make clear the pounding procedure, dynamic analysis for the superstructure was conducted. Based on the theoretical formula about momentum and impulse, the affected factors on pounding force have been discussed. Pounding velocity and rotational angel have been regarded as the determining factors of pounding force. The improving measures of bridge structure can be conducted to reduce the pounding force.
