Abstract:
Reinforcement corrosion constitutes a major threat to the durability and safety of concrete infrastructure. While the effect of reinforcement corrosion on the flexural strength and bond of reinforcement in reinforced concrete beams has been studied, more research is needed on the effect of corrosion of stirrups and longitudinal reinforcement on their shear strength. This paper focuses on the shear strength of reinforced concrete beams with a shear span to effective depth ratio 2.5.
A review of experimental investigations on the behavior of reinforced concrete beams subjected to varying levels of reinforcement corrosion is summarized. The ACI CODE-318-25 shear design provisions are assessed by comparing experimental results with code-calculated strengths. Modifications to improve the safety of the current ACI CODE-318 approach are proposed to estimate the shear strength of slender reinforced concrete beams with corrosion damage.
