Abstract

Abstract

Experiments on reactive powder concrete-filled steel tube (RPC-FST) specimens after exposure to high temperature were performed by using a split Hopkinson pressure bar (SHPB) apparatus, and the influences of strain rate effects and temperature effects on the dynamic behaviors of RPC-FST were investigated. Test results show that the RPC-FST specimens after exposure to high temperature have excellent impact-resistance, ductility and integrity. The strain rate effects of the RPC-FST specimens are weaker than those of the RPC specimens under impact loading. The peak stress of the RPC-FST specimens increases as the temperature increases, and the deformation capability and impact-resistance increase. The dynamic increase factor (DIF) increases as the temperature increases. It means that the strain rate effects of RPC-FST become more obvious after exposure to high temperature.
