| Abstract: | The model for Yuxi bridge was constructed on the basis of ANSYS.The research for the dynamic characteristics was made by mode analysis.Taking the arch crown and quarter section of the arch ring as key sections,by exerting Taft seismic wave on the bridge,the stress,displacement and the maximal moment of key sections were computated by the time-history analysis and the TMD equipment was used to reduce the seismic intensity. |

| Keywords: | dynamic characteristics mode time-history response analysis |
