Structure Design And Construction Control Of Steel Bridge

Based on summing up the design and construction control technology of steel bridge of home and abroad, taking ChiZhou QingFeng steel bridge as a project background, this paper has a particular study on the designing and construction controlling for the steel bridge.The following aspects have been studied on the designing and construction controlling for the steel arch bridge. Stating the general situation of ChiZhou QingFeng steel bridge 's projecting;Discussing the characteristic of design for the steel bridge, the system of structure, the size of the bond parts and the best construction project was determined;Expatiation the application of MIDAS/Civil in the modeling of ChiZhou QingFeng steel bridge ,and using the the finite element analysis software MIDAS/Civil to analyze the structure of the steel box arch bridge;Research on the Eigenvalue Analysis and the buckling analysis at Completion Stage. Analysing the stress of the girder and arch under the stage of self-weight situation and six load situation. Checking the stree of the structure. Adopting the construction control method to simulate calculation in the four construction stages.Studied internal force and transform of four construction stages, make sure the general precamber of the main beam,the side beam and three arches.
