Taking Wuhan Erqi Yangtze River Bridge as an example, based on link element, shell element, and beam element, a double beam nonlinear finite element model is purposed using popular finite analyzing software ANSYS. The internal force and deformation characteristics of composite beam cable-stayed bridge with three towers is analyzed by double beam model, and compared to the single beam. The results show that the double beam nonlinear FE model, which have less freedom and conveniently calculate, can be used to well analyze the nonlinear of composite beam cable-stayed bridge with three towers.
