Considering the change of bond strength between corroded steel and concrete, flexural carrying capacity of corroded reinforced concrete (RC) beam was calculated. On the basis of the condition of equilibrium of forces and compatibility of deformations for the whole beam, a model for the prediction of flexural carrying capacity of the corroded RC beam was proposed. Comparison of the model’s predictions with the experimental results published in the literature shows the practicality of the proposed method.
