In this paper, research on bond and anchorage of reinforcement in high strength concrete were reviewed. They were classified to three groups: research on bond capacity with splitting of surrounding concrete, bond deterioration of bars passing through beam-column joints and anchorage capacity of hooked bars in beam-column joints. A characteristic property of low tensile strength relative to the high compressive strength results in a small increase of bond and anchorage capacity if the failure mode is governed by concrete splitting. Transverse reinforcement is more important for high strength concrete. The effect of concrete strength is more for the bond which failed in concrete crushing or direct shearing at the interface, such as the bar passing through the joint. High compressive strength and high rigidity of stress-strain curve make the local bond-slip curve stiffer. Low sedimentation and low bleeding effects make the top bar effect small. By analyzing available research, bond and anchorage capacities were evaluated quantitatively for practical design use.
