ESTIMATION OF RESIDUAL RELIABILITY OF REINFORCED CONCRETE BRIDGE WITH UNAVAILABLE DESIGN DATA

摘要：

In this paper,the damage modal of steel corrosion and fatigue is established on thebasis of durability and time variation reliability of reinforced concrete to evaluation thecharacteristics of existing RC railway bridges. The model of variation of structural resistanceforce is set up which taken into the fatigue,rust,carbonation of concrete. The reliability andresidual life of the bridge are evaluated by the model,the result shows good correlation withthe resistance force and can offer important information for bridge maintenance andreinforcement. This method is a reference method for bridge structure reliability assessmentcan improves efficiency of the bridges evaluation.
