normal-weight concrete were obtained. It was established that an increase in concrete strength is accompanied by a proportional increase in the bond capacity between sickle-shaped reinforcement and concrete. A linear relationship between the maximum tangential bond stresses and concrete strength was identified, demonstrating good agreement with the experimental results. The proposed linear relationship may be applied in the design of reinforced concrete structures to calculate the ultimate bond strength of sickle-shaped steel reinforcement embedded in normal-weight concretes of various strength classes.
