RESIDUAL FLEXURAL STRENGTH OF CORRODED

2021-3-1  In view of the fact that corrosion damage reduces the strength of a reinforced concrete element, it is of great interest to develop a model that can be used to predict the relative flexural strength of corroded concrete members. The need for the prediction of the relative strength often arises to determine the underlying safety of the corroded members and to decide when the repair or strengthening
