Nonlinear static analysis of cable-stayed bridge

To the middling span cable-stayed bridge with single tower, it is very outstanding for material nonlinearity which caused by nonlinear properties of the material. So we must calculate the effects of the material nonlinearity which caused by nonlinear properties of the material when we calculate the geometry nonlinear effects to many middling span cable-stayed bridge with single tower. The other issue is that many people adopt simplified models in the course of the nonlinear static analysis to the bridge which can not get the particular law of the stress and the deformation of the bridge. Here, we take Jilin Linjiangmen cable-stayed bridge as an example, a new analysis model is established which adopts SOLID65 and LINK10 to simulate the concrete and the cables by ANSYS. The method breaks through the former form of the analysis model.
