Abstract
This study was carried out to investigate quantitatively the relationship between the degree of reinforcement corrosion and the mechanical properties of reinforcement. In the experiment, the tensile test of corroded reinforcement was conducted at the different stage of the degree of reinforcement corrosion. As a result, it was found that the chloride-induced corrosion induce the pitting and the corrosion using electrical current induce the uniform corrosion. As the degree of reinforcement corrosion increased, the nominal yield point and nominal elastic modulus both decreased. Also, there were very high correlations between the degree of reinforcement corrosion and the mechanical properties of reinforcement. We could make the material constitutive laws for the mechanical properties of reinforcement as a function of the degree of reinforcement corrosion to analyze the damaged RC members with reinforcement corrosion using finite element method.
