Stirrups corrosion causes damage effects on the shear response of reinforced concrete elements. Such damage mainly includes cracking and spalling of concrete in the cover, and reduction of the cross-sectional area of the reinforcing steel. The need for tools able to predict the reduction of the load-bearing capacity of reinforced concrete element has led to several formulations based on the numerical regression of available experimental results. This paper proposes a mechanical model for the prediction of the shear response of reinforced concrete slender beams with corroded reinforcement. The proposed procedure, based on the Modified Compression Field Theory, can reproduce the entire load-displacement curve. The corrosion effects on the effective beam width and rebar cross-section are taken into account. The accuracy of the proposed model is assessed using a database of sixty-two specimens. The proposed model achieves accurate results.
