| As China's economic development and people's increasing demand for urban landscape in recent years, some cities in China to build special-shaped cable-stayed bridge. Shaped not only able to complete with conventional cable-stayed bridge traffic capacity, and because the tower is handsome in appearance, fit to be a landmark of the city, so by the owners and design professionals of all ages, and to be applied in large projects.This article, based on the theoretical analysis, to Xining City-sea bridge project Huangshui rely on finite element analysis software using MIDAS/CIVIL2010, considering all the material parameters in the accurate, cross-sectional size, based on the finite element analysis model of the whole. Taking into account the design load, based on detailed simulation of the construction phase. The shaped bridge, the role of the design load combinations, each cable of the cable force the root, the fulcrum of the support reaction force, cross-section internal force, the displacement of a detailed analysis, the overall abnormal mechanical characteristics of cable-stayed bridge has A clear understanding.This paper also established local finite element analysis of steel box girder model, a simulation analysis of steel box girders. The combination of the design load under the action of the steel anchor box, steel box girder webs, roof displacement; steel anchor box, steel box girder webs, roof, floor and U-rib, diaphragm stress simulation analysis The detail of the steel box with a clear understanding of the force.Another article, also established a finite element analysis of steel anchor box model, the accurate simulation of steel anchor design load cases and boundary conditions, based on the anchor box of steel were simulated. The combination of the design load under the action of the steel anchor box, pressure plates, side panels, anchorage under the vertical stiffeners, transverse stiffeners under anchorage, end plates, end plates interconnect, concrete tower wall stress of a detailed analysis of the steel Detail anchor box with a clear understanding of the force. |
