| Abstract: | Considering geometric nonlinearation of the bridge during construction,structural behavior of the concrete filled steel tube stiff skeleton of Jinhe bridge over Yalong River in Yanyuan with a span of 170m is analyzed,with the aid of the mixed structure model with the shell,truss and beam member using finite element method.The internal force,deformation and stability during construction of the arch rib of the bridge are also discussed in detail. |
