Abstract

In this study, the experimental estimation for influence of the shear and anchor reinforcement on the characteristics of residual strength of RC beams, of which failure mode is flexural under the non-corrosion, with corrosion was carried out. It is noted that the residual flexural behavior is different due to the occurrence of non-uniformity of main reinforcement corrosion. In case of uniform corrosion, the flexural failure of RC beams, of which the residual shear reinforcement is sufficient, occurs, on the other hand, the brittle failure occurs by the stress transfer to the shear and anchorage region of main reinforcement. In case of non-uniform corrosion, the flexural failure occurs due to the localized deformation on the region of remarkable corrosion.
