| Abstract: | Using the program which takes into account geometrical nonlinear behavior,the structure static properties are analyzed under different load with different design parameters such as the ratio of suspension to span,the ratio of height to span,the number of auxiliary piles and structure support system,which takes completed bridge state as initial state.These conclusions drawn from the analysis offer some reference to the design parameters of this type of bridge. |
