One of major causes responsible for the performance loss of reinforced concrete structures is the corrosion phenomenon. Thereby, taking into account the local effects of the steel/concrete interface is of primary importance to predict properly the response of corroded reinforced concrete structures. A multifiber-based model including the steel/concrete interface is proposed. This interface model allows taking into consideration the bond strength variation due to corrosion. Such an approach leads to reasonable computational costs which a powerful feature of the model. A numerical study of beams already studied in the French project 'benchmark des poutres de la Rance' is proposed in order to show the efficiency and reliability of the proposed model.
