Study on Moment Redistribution in Statically Indeterminate Corroded Reinforced Concrete Beams
Incoming article date: 09.12.2023This article investigates the moment redistribution behavior in corroded reinforced concrete (RC) beams. previous studies by different authors are reviewed, which shed light on the behavior of corroded statically indeterminate RC elements. The corrosion effects on the ultimate strength, deflection, and moment redistribution ratios are examined. The application of axial loads and location and severity of corrosion allowed for a comprehensive discussion of the moment redistribution behavior. The results showed that continuous RC beams with corroded reinforcement behave differently than simply supported RC beams. The corrosion process also affected the moment redistribution, providing additional safety to the RC structures. Existing research in this area is limited, and further investigations are required to address this knowledge gap and improve the understanding of the mechanism of moment redistribution in continuous corroded RC beams.
