The pull-out tests for bonding between rebar with inside strain gauges and steel fibre reinforced concrete (SFRC) were carried out to study the bond properties of specimens with varying concrete strengths. Based on the analysis of measured rebar strain, the distribution function of bond stress performed in cubic smooth spline was established. The distribution of bond stress and relative slip in bonded segment was obtained under the action of load at each stage, and the effects of steel fibre and concrete strength on bond properties were further analyzed. The results indicate that with the increasing of volume fraction of steel fibers and concrete strength, the bond stress of bonding specimens next to loaded end is improved and the ultimate bond stress moves to loaded end in general. Meanwhile, the slip at loaded end and free end were reduced. Finally, the bond-slip constitutive model reflecting the interaction process of rebar and SFRC was proposed.
