Abstract

This paper presents an experimental study on effect of corrosion on durability performance of circular Steel Strapping Tensioning Technique (SSTT)-confined concrete tested under uniaxial compression. A total of 13 specimens, including 11 confined specimens and 2 plain specimens were tested in this study. The main parameters were prestressing level and corrosion protection. Corrosion was simulated through impressed current accelerated corrosion technique. The experimental results indicated that influence of corrosion was insignificant on peak strength and slight reduction in deformation ability to corroded circular SSTT-confined concrete under low corrosion severity. It was observed that Zn-Al-Cd ingot and long-oil alkyd paint coating shows good protection ability, while 6061 aluminum alloy and 99.9% pure magnesium is not suitable to be used as corrosion protection system. Based on regression analysis, prediction models for peak stress and peak strain for circular corroded SSTT-confined concrete were proposed.
