Abstract

Because the bond strength between a reinforcement and concrete is affected by various factors, including the compressive strength of the concrete, concrete cover thickness and reinforcement geometry, the bond mechanism is very complicated. This study proposed an analytical model that estimates the bond strength of the steel reinforcement considering both the splitting and pullout failure modes based on mathematical modeling of the stress field in reinforcement and the surrounding concrete. The results of the comparison between the analytical results obtained by the proposed model and test results reported in the literature showed that the proposed model can adequately estimate the bond failure mode and bond strength of the collected test specimens.
