SinoXivMechanical Properties Degradation of Ferritic Stainless steel (410L) and Carbon Steel Reinforced Concrete Beam due to Corrosion
Abstract
Corrosion-induced deterioration of RC structures is a major concern, especially in chloride-rich environments. This study examines the flexural behavior of RC beams reinforced with Ferritic stainless steel (410L) and carbon steel (Fe500D) rebars under accelerated corrosion through four-point bending tests. Results show that both rebar types experience reductions in yield load, ultimate load, and deformation capacity with increasing corrosion. CS beams exhibit greater load capacity loss at moderate corrosion levels (up to 10% mass loss), while SS beams suffer more severe strength reductions at higher corrosion levels (above 20%) due to pitting corrosion. Uncorroded SS beams demonstrate higher yield and ultimate loads but lower ultimate deformation capacity than CS beams. These findings highlight the need for corrosion-specific design considerations for SS-reinforced RC beams and emphasize optimizing predictive models to maximize the benefits of stainless-steel reinforcement in RC structures.
