Study on Residual Flexural Strength of RC Beams with Corrosion of Reinforcement

Abstract

In this study, experimental and analytical estimation of residual flexural strength of RC beams with reinforcement corrosion was carried out. As a result, it is noted that the factors, which influence on residual flexural strength and failure behavior of RC beams were not only corrosion rate, bond stress behavior but also the corrosive crack characteristics of concrete. Moreover, it seems impossible to estimate the characteristics of bond splitting failure along reinforcement and sudden drop of external forces in the current analysis, in which only corrosion rate and bond stresses are taken into consideration.
