Residual Flexural Capacity of Corroded Prestressed Reinforced Concrete Beams
Infrastructures and industrial buildings are commonly exposed to aggressive environments and damaged by corrosion. In prestressed reinforced concrete structures, the potential risks of corrosion could be severe since reinforcements are already subjected to high amounts of stress and, consequently, their load-bearing capacity could abruptly decrease. In recent years, some experimental studies have been conducted to explore the flexural behavior of corroded pretensioned reinforced concrete (PRC) beams, investigating several aspects of residual structural performance. Although many studies have been done in this area, there is no concise paper reviewing the state-of-the-art research. Accordingly, the main objective of this paper is to provide a review of the available experimental tests for residual capacity assessment of corroded PRC beams. Based on the state-of-the-art review, a degradation law for the flexural strength of corroded PRC beams is suggested. ; The work is part of the research project “OPTION-Effect of corrosion on prestressed reinforced concrete beam” between OsloMet–Oslo Metropolitan University and Niccolò Cusano University. OPTION has received funding from the Department of Civil Engineering and Energy Technology, OsloMet–Oslo Metropolitan University. ; publishedVersion
