An experimental study was conducted to evaluate bond splitting behavior of corroded longitudinal bars in reinforced concrete beam with non-corroded stirrups. The pull-out tests were carried out to investigate effect corrosion through electrochemical corrosion process on bond splitting capacity, bond-slip relations and mode of failure including the influence of stirrup, bar position, and concrete strength. The test results showed substantial contribution of stirrups on residual bond splitting capacity and found that lower bond strength and small slip at maximum bond stress for corroded bars
