摘要：
The cable-stayed concrete filled steel tube arch bridge is a new kind of bridge which is alteration from hybrid truss arch bridge. It combines the structural virtue of concrete filled steel tube (CFST) arch bridge and cable-stayed bridge. Compared with hybrid truss arch bridge, the rigid inclined chords are replaced with the cable that can change tension force. It is possible that the change of cable's tension force can control arch axes' elevation and adjust the internal force of arch ring. In this paper, the model of Tianzishan Bridge with finite element method is built. The bending deflection and internal force are computed and researched. Its basic character is that CFST arch rings are main bearing structure component.
