Prediction Method of the Load Resisting Mechanisms in the Corroded RC Beams

Abstract:

The failure mode of the corroded RC beam may shift from designed failure mode to others failure mode, as the load resisting mechanism changes due to the corrosion ratio of rebars. In this study, the load resisting mechanism and the failure mode of the corroded RC beam were investigated based on the bond performance. If the corroded RC beam is non-uniformly corroded, the beam suffers beam action and fails in flexural failure. Otherwise, the load resisting mechanism and the failure mode depend on the corrosion ratio of bottom portion stirrups. Moreover, the decision point is proposed to predict the load resisting mechanisms in the corroded RC beam.
