| Abstract: | In this paper,the dynamic load test of Beijing Youyi Bridge is introduced,with the help of FEM(Finite Element Method) software Midas/Civil,which is especially applied for the bridge,the simulated model of the Youyi Bridge is built,the assessment analysis based on the tests data and theoretical calculations showed that the dynamic stiffness of the bridge depressed greatly,it cannot meet the demand of the load-bearing capacity and need strengthen and maintain. |
