| Abstract: | Taking Chongqing Yuzui the Yangtze River Bridge as investigated subject its spatial finite element model is built. Eigenvalue analysis, time history analysis of dynamic load and seismic response analysis of the bridge in finished phase are made. In the end the impacts of vehicle speed on dynamic response of bridge are studied. |
