The corrosion effect on tensile strength of RC members is very important to region prone to high corrosion conditions. In this article a study concerning bond behavior, crack pattern, crack spacing, and tension stiffening of RC members is presented. For this purpose, a comprehensive experimental program including 58 reinforced concrete cylinders with different concrete covers and reinforcement ratios under various corrosion rates is conducted. The specimens are located in large tub containing water and salt (5% salt solution) with a device for accelerated corrosion production. For each specimen, the variation of total tensile strength versus its average strain is plotted and the member behavior at various load levels is investigated. Average crack spacing, and maximum bond stress developed at each corrosion level are studied and their appropriate relationships are proposed. The main parameters considered in this investigation are: corrosion rate (Cw), reinforcement diameter (d), reinforcement ratio (p), clear concrete cover (c), and d/p.
