A simplified numerical approach of global behaviour of RC beams degraded by corrosion

Résumé

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.
