The Research Of Reliability For The Reinforced Concrete Beam-Bridge Strengthended

At present, domestic and foreign regarding already has the reinforced concrete beam-bridge reliability research to be many, reliability analysis theory is also quite perfect, but after reinforced concrete beam-bridge strengthened reliability research and the material are few, how to act according to the existing theory after the reinforced concrete beam-bridge strengthened reliability carries on the analysis computation appears very essential.This article embarks from the structure reliability's elementary theory, the union project example, after summaried sticks the steel reinforcement, the reinforced concrete beam-bridge reliability analysis method.The paper elaborated structural unit's reliability basic principle in detail, after sticking the steel reinforcement reinforced concrete beam-bridge, has carried on the analysis computation to the domestic massive reinforcement experiment material,after obtaining sticks the steel reinforcement,the reinforced concrete beam-bridge member's computation pattern uncertainty coefficient statistical parameter.After sticking the steel reinforcement the reinforced concrete beam-bridge member resisting force influencing factor has carried on the analysis, and refers to the existing structure the resisting force statistical analysis method, in the consideration structure damage to the resisting force weaken influence's foundation,after reinforcing the structural unit resisting force partial parameters has carried on the revision,after having established stuck the steel reinforcement, the reinforced concrete beam-bridge member resisting force probabilistic model, gave the statistical parameter according to the reliability unified standards to establish the load effect probabilistic model.According to the above method, through stuck the steel reinforcement after one reinforced concrete simple support T liang analyzes the computation, after summaried stuck the steel reinforcement, the reinforced concrete beam-bridge reliable target solution method and the partial parameters to the reliable target influence and the change rule. This article's solution may supply performance evaluation reference to the strengthened beam-bridge.
