Durability Life Prediction Of Concrete Stuctures & Reliability Analysis And Study

In this paper, according to the more and more serious problem of durability of concrete structures, based on native and foreign experts's achievements about durability of concrete structures, introduce the elementary theory and achievements are introduced from the theory of reliability about concrete structures,durability life prediction of concrete structures,under air environment condition and under erosion environment condition prediction structures durability life methods.Key elaboration on the computational methods of reinforced concrete structures dynamic reliability,on the basis of steel bar rust eclipse mechanism, two methods of life prediction: under the air environment, the length of concrete carbonization achieved steel bar surface, in this kind condition, the life of concrete structures terminate, this in a one method; under erosion environment, chloride diffusion concrete causes steel corrosion, goes a step further causes concrete crack, in this lind condition, the life of concrete structures terminate, we proposed the formula of life prediction.
