In recent years, the necessity and importance of maintenance management of RC structure have been recognized.Under such situation, reduction of maintenance management cost has been strongly required and life cycle cost (LCC) has been paid attention to. However, at the present stage, the calculation method and the evaluation technique of LCC have not been fully established. Moreover, LCC will be greatly influenced with social and economical conditions. The paper discussed LCC of RC members which were exposed to sea environments. Those members might be damaged due to corrosion of reinforcing bars and might be obliged to repair. Calculation method and evaluation of LCC were scrutinized especially in consideration of the price increase rate and the interest rate of capital which might be influential factors of LCC for the repairing methods. Finally, the adequate maintenance system of LCC regarding repairing method and repairing time was proposed.
