Effects of Stirrups Corrosion on the Shear Strength of RC Beams

Based on different theories (plasticity theory, modified compression field theory and compression chord capacity theory), this paper investigates the effects of corrosion of the transverse reinforcement on the shear strength of reinforced concrete beams. The effects of corrosion of the transverse reinforcement are firstly described and, then, adequately introduced in the formulations of the plasticity and modified compression field theories. The considered formulations are applied to a set of RC beams tested in laboratory by other researchers and a comparison is first drawn between the shear strength values resulting from the considered models and the shear strength resulting from the laboratory tests. Then, the effects of corrosion on the mechanical parameters involved in the ultimate response of the examined reinforced concrete beams are investigated.
