A reliability-based durability design for reinforced concrete (RC) structures in a marine environment based on the partial factors format is proposed. In the proposed method, RC structures are designed so that the time to the occurrence of the specified amount of steel corrosion provided by the partial factor and design criterion is longer than the design lifetime. By using the proposed method, RC structures satisfy the target durability reliability level without any probabilistic calculations. Also, the effects of uncertainties involved in the evaluation of the amount of steel corrosion in durability design of RC structures are discussed based on the sensitivity analysis.
