Executive Summary | This paper studied experimentally and analytically the tension stiffening and cracking behavior of corroded uni-axial RC members. Eighteen RC members of 2.0m in length were prepared for the experimental tests and thirteen of them had experienced different levels of impressed current deterioration. Test variables included rebar type, rebar diameter, and transverse confinement condition. The steel corrosion and cracking distributing properties, corrosion-induced bond loss, and the corrosion-induced tension stiffening deterioration were investigated in details. It was found through the tests that the localized deformations, namely the corrosion-induced cracks and it-affected loading cracks, are highly correlated with the un-uniformity of steel corrosion. Moreover, it was concluded that, compared to the losses of steel cross-section and effective concrete cover, the bond loss-induced tension stiffening deterioration may be not a critical factor responsible for the |
