Dynamic test and finite element analysis of A Existing Arch Bridge with Steel-pipe Concrete

桥梁结构的动力特性(振型、频率和阻尼)是桥梁承载能力评定的重要参数,同时也是识别桥梁结构工作性能和桥梁抗震分析的重要参数。

The dynamic behavior of bridge（vibration mode,frequency and damp） is an important parameter of assessing the carrying capacity of bridge.And it is an important parameter of the identifying the working performance of bridge and the aseismic analysis of bridge.According to the dynamic test and spatial entity finite element analysis research of the Arch Bridge with Steel-pipe Concrete（Hai-hu bridge）,thereby concluding the safe bearing capacity and service condition of this bridge overall structure,this thesis is offered a reference for the capability appraisal of similar bridges.
