Abstract

In order to obtain the optimal values of cable force, and determine the reasonable finished bridge state for large span Cable-stayed bridge with hybrid girder, the space finite element simulation analysis model of the whole bridge is established, considering the characteristics of its span arrangement and structure, analysis the method and basic principles for determining the reasonable finished bridge state, calculated with the influence matrix method and minimum bending energy method, and the objective function is minimization the maximum displacement of tower and girder. Through calculation, the stress of the main pylon, the main girder and the stay cables in the finished state and the operating state can satisfy the requirements of standard, the reasonable finished state of cable-stayed bridge in accordance with the requirements.
