The aim of the present research is to assess the dynamic performance of bond-slip between reinforcing steel bar and concrete. Precisely, the sensitivity of the bond stress-displacement relationship in the interface between reinforcing steel bar and concrete to strain rate is investigated. In this paper, the reinforcing steel bar/concrete specimens were tested in dynamic push-out experiments with modified split Hopkinson pressure bar (SHPB) system. The incident bar was used to apply compressive loading to single steel bar embedded in a surrounding concrete. Using this technique, the debonding progress was analyzed. Besides, the effect of loading rate and effective depth on the push-out tests was studied with the impact velocities in the range of 9 m/s - 29 m/s. It is seen that maximum push-out force increases with increasing loading rate. In addition, the dynamic interface bond force does not proportionally increase with the effective depth of steel bar.

Steel and concrete are poured together with a certain way which can be regarded as a fiber reinforced composite material. For this composite material, the issues of bond and pull-out are very important. The bond property of reinforced concrete at normal temperature is different from the property at elevated temperature. The exposure of reinforced concrete structural elements to high temperatures during an aggressive fire leads to significant losses in its structural capacity due to the reduction in the strength of the concrete, possible plastic deformation of embedded steel and most importantly loss of bond between reinforcing steel and concrete. This paper aims to investigate the influence of high temperature to the bond slip of reinforced concrete. The bond behavior between reinforced concrete and reinforcing steel bars was evaluated under elevated temperatures. Based on the energy principle, the debonding criterion of the steel bars and concrete at a high temperature is derived. It was concluded that the bond slip should be included in order to reflect the unloading of the concrete surrounding the reinforcing steel exposed to fire temperature.
