【摘要】 介绍了北京市友谊大桥的动载试验,并借助桥梁专用有限元计算分析软件Midas/Civil建立友谊大桥仿真模型,将理论分析计算值与动载试验实测值对比分析,对比分析表明该桥整体动刚度降低,已不满足承载能力要求,需要对该桥进行加固维修。更多还原

【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.更多还原
