The life prediction of reinforced concrete structure is one of very useful technique to estimate durability of the structure. It needs quantitative evaluation of deterioration which progresses with the passing of the years and of the influences of various factors on deterioration. Herein, the life prediction method of reinforced concrete member is introduced based on the reinforcement corrosion due to action of chloride. The life of reinforced concrete member can be defined as the span that the structure needs to be a certain limit state from its construction. Two evaluation models, that is, physical model for reinforcement corrosion in concrete and reliability-based model for reduction of member resistance are conducted concerning two limit state, that is, cracking longitudinally due to reinforcement corrosion and the ultimate limit state for flexural resistance of member, respectively. These models enable us to predict the life of reinforced concrete member.
