| Abstract: | For enhancing the safety of the small-radius curved girder bridge, a 3D finite element soft- ware program is used to calculate and compare the internal force and displacement of bridges with dif- ferent radius of curvature. The relationship between central angle and internal force and displacement is analyzed. Finally, the corresponding suggestions for the design and calculation are put forward. |
