Influence of chloride corrosion on tension capacity of rebars

Abstract

The reinforcement corrosion is the pitting corrosion of chloride corrosion. Hence, in this study, the variations of reinforcement tensile strength due to stress concentration of pitting corrosion are analyzed. The stress concentration consequence of corrosion on the reinforcement tensile capacity is studied utilizing tension tests and creating different ABAQUS software models. According to the modelling in various corrosion depths, strength reduction is less than 5% in corrosion with pit radius to reinforcement diameter ratio up to 0.3 and for corrosions higher than 0.4, the measure of capacity reduction is increased more to 30%.
