Abstract

This paper investigated the bonding and cracking behavior of eighteen 2.0m long uni-axial RC members, thirteen of which had experienced different levels of impressed current deterioration. cracks. It was found that corrosion-induced bond decay and the resulting-in tension stiffening show significantly different rates in loss with the increase of the corrosion level. Compared to tension stiffening deterioration, localized cracking deformations related to the corrosion un-uniformity are more critical for the evaluation of serviceability deterioration in the corroded RC members.
