| Abstract: | Haikou Bridge is a concrete-filled steel tubular arch bridge with a main span of 150m.Taking that bridge as an example,based on the software ANSYS,two kinds of spatial finite element models for the bridge were respectively established,under the consideration of the pier bases concretion and the interaction between the soil and the pile.Calculation analyses results of natural vibration of the two models are comparatively analyzed.The establishment method of the two models of the half-through concrete-filled steel tubular arch bridge is provided,which can be reference for relative research. |

| Keywords: | natural vibration half-through concrete-filled steel tubular arch bridge finite element method soil-pile-structure interaction |
