| Abstract: | For enhancing the safety of the small-radius curved girder bridge,a 3D finite element software program is used to calculate and compare the internal force and displacement of bridges with different 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. |
