DURABILITY ANALYTICAL METHOD FOR CONCRETE BRIDGE STRUCTURES

摘要：

At present,most of the researches on durability of concrete bridges are of membersand qualitative. For the purpose of quantitative analysis on the discipline of degradation ofconcrete bridge structures,a durability analytical method for concrete bridges is built bynumerical simulation on the quantification models of environmental effect and thedegradation models of concrete carbonization,chloride attack and steel corrosion,etc. Thefollowing method,which can consider the influence of deterioration of mechanical propertiesof materials and members on the degradation of mechanical properties of integral structure,accomplishes the goal of durability analysis on complex concrete bridge structures. Thus,theparametric analysis on durability of concrete bridges can be made by the method,which cangive advices in durability designs.
