This paper presents the results of the experimental investigations on the influence of concrete strength, and confinement effect of different arrangements of hoops on the bond-slip relationship between reinforcing steel bars and concrete. The Pull-out tests according to the recommendations of RILEM CEB RC6 were conducted to determine the bond strength-slips relationship. A set of 27 specimens were prepared for the testing with two main parameters, including concrete strength and stirrup spacing. Based on the current test results, the effects of such variable of interest on the behavior of RC structural elements are discussed.
