Abstract
The dynamic behaviour of normal strength concrete-filled steel tubes (CFT) at elevated temperatures up to 800 °C under axial impact loading was experimentally studied by using a newly developed spilt Hopkinson pressure bar (SHPB) together with an electrical furnace. The effects of high temperature, impact velocity, steel ratio and slenderness ratio on the impact behaviour of CFT at elevated temperatures were experimentally studied. The stress and strain time history curves of the tested specimens were recorded to analyze the impact behaviour of CFT at elevated temperatures. The failure modes and the effects of the experimental parameters on the impact resistance of CFT are discussed. The test results showed that normal strength concrete-filled steel tube at elevated temperatures had a more excellent impact resistance in the paper than that described in Huo et al. (2009). A simplified calculation method was updated by introducing the reasonable dynamic increase factor model of hot concrete to reasonably assess the impact resistance of CFT at elevated temperatures.
