Error sensibility analysis of finite element model is widely used to obtain high-accuracy model, which is very important for structure simulation, damage identification and health diagnosis. ANSYS finite element software is used to build the initial model of three-span concrete-filled steel tubular arch bridge, and calculate the dynamic and static response value which is the basic compare parameters. Impact of different modeling factors to local dynamic and static response value of model is researched and the sensitivity of each response error to different modeling factors is summarized. In all the factors of modeling, the most important factor influencing the dynamic and static response of this bridge is the synergy between steel tubular and concrete. The result can be the reference when the concrete filled steel tubular arch bridge model is built. |
