To evaluate the remaining service life and determine the appropriate timing and method for repair and reinforcement for the reinforced concrete (RC) structures, it is important to quantitatively evaluate the residual load capacity of RC structures deteriorated by rebar corrosion due to chloride attack or neutralization. There have been many studies on the load capacity during static loadings. However, for disaster-prone areas, the evaluation of the residual load should be conducted also against the dynamic and impact loads. In this study, RC slab specimens and RC beam specimens with reinforcement corrosion is prepared with electrolytic corrosion. To clarify the impact resistance of the RC members with rebar corrosion, a falling weight impact experiment is conducted on the RC beam specimens and a medium velocity impact test is conducted on the RC slab specimens. Based on the experimental results, the relationship between the degree of deterioration and impact resistance is clarified.
