Analysis Of Reinforcement Method And Bearing Capacity Of Reinforced Concrete Beam Bridge

In the bridge structure system, the most used is girder bridge. Prestressed concrete continuous box girder bridge, as a kind of beam bridge, it is mainly used for highway Bridges and cities.Box girder with good integrity and continuity and larger stiffness, but it also exists the girder crack, across the middle and lower scratching, etcCentered on the Wo Long bridge reinforcement, this paper has carried on the following work:(1) summarizes the bridge diseases, mainly introduced the box girder cracks and the reason of lower scratching.(2) summarizes the main reinforcement methods of bridge, expounds the mechanism of reinforcement reinforcement method and the applicable scope, the theory basis of pasting steel plate is introduced in detail.(3) introduced the force analysis of the section, box, according to the appearance of the Wo Long bridge test results based on MIDAS/Civil analysis software to establish analysis model of continuous box girder bridge, it is concluded that the static characteristics, and main control section of the bridge bending moment, stress and displacement. Compared before and after reinforcement bridge on static characteristics, control section bending moment, the strengthening effect of the stress, displacement, etc, and make the bridge reinforcement effect assessment.(4) taking the fracture process and paste the construction technology of the steel plate, are briefly introduced in this paper.Wo Long bridge reinforcement research papers from the background project, a comprehensive beam Bridges of diseases.it is discussed and its influence factors, the main reinforcement method and the applicable scope, the reinforcement mechanism of continuous box girder bridge cracks and across the middle and lower of the cause of the scratch, pasting steel reinforcement based on theoretical calculation, calculation and analysis software and a series of problems, and through the project example to reflect and prove the research achievements of this thesis. This thesis research results of continuous box bridge on the...
