| Abstract: | The geometry nonlinear source and behavior for large span cable stayed bridge was discussed. Hence, some researching questions about nonlinear of large span cable stayed bridge were put forward. Dealing with the combination structure of girder tower, a set of formulation for beam element was derived. And based on the modified Lagrange method, a set of nonlinear finite element equations was built and program were made. The program are provided to show that the proposed method is efficient and possesses the accuracy required by Yueyang Dongtinghu Bridge, and has good suitability in engineering. |
