Abstract:
The method of improvement response surface was put forward to study the reliability assessment on existing PC bridge. By using the neural network model fitting function, the reliability index was calculated with JC method and the reliability analysis was done for bridge structure component. An engineering case analysis shows that the neural network model can express the complex bearing capacity function easily. The reliability index of the upper structure calculation value gradually decreases along with the increase of using years, which explains the bridge's resistance degradation. The reliability calculation of bearing capacity of PC bridge by using the method is feasible. 4 tabs, 1 fig, 9 refs.
