| Abstract: | In this paper, based on natural characteristic of prestressed Cable-Arch structure, Ansys FEM program was used to simulate its geometrical nonlinear behavior with beam element and cable element. With Newton-Raphson and arc-length calculation method, this paper has made research on effect of prestress in cable. This work gives some reference for technical application of prestressed Cable-Arch structure. |
