Research for the Structure System of Curved Wide Extra-Dosed Cable-Stayed Bridge

Abstract:

This paper is based on some curved wide extra-dosed cable-stayed bridge, and the finite element software MIDAS/CIVIL is applied to set up three different system models of semi-floating system, pylon-girder consolidation system and rigid frame system according to the practice engineering background. Compared the internal forces and displacements in three systems under dead load, temperature load and live load, conclusions can be drawn as, the overall stiffness of rigid-frame system is the largest, its deformation is the least under dead load and live load, but it is sensitive to temperature load which can cause large second internal force. According to the overall structure performance of three different systems, it is better understanding their superiority to different application range, which can be a reference for designing in the future.
