In this paper, the effects of chloride corrosion of steel reinforcement on the axial compressive strength and the ultimate strain of concrete materials in reinforced concrete columns have been investigated experimentally. In addition, the effects of reduction in the effective mechanical properties of concrete materials on moment‐curvature response of a corroded bridge pier were numerically studied. This investigation has resulted in clear quantification of the relationship between the degree of reinforcement corrosion and the effective compression strength and ultimate strain of unconfined concrete. The results clearly show that corrosion of steel reinforcement resulted in a deterioration of the effective axial compression strength and ultimate strain of column's concrete cover.
