    Abstract: The formula for calculating corrosion ratio of areinforced bar in reinforced concrete members at the moment of cracking isdeduced by using mechanical analysis, and taking account of concrete plasticity andinterface crack between concrete and the reinforced bar. The factors affectingthe corrosion ratio are analyzed. The method may be used fordurability evaluation of concrete structures and prediction of service lifeof concrete structures.
