Abstract

Abstract

A kind of hollow reinforced concrete column with inner octagon steel tube is considered as the object of this study. The experiments are carried out using a large drop testing machine which was designed by ourselves. The analysis parameters included the boundary conditions, the impact heights and the axial compression ratios. During the experiments, the time history curves of the impact force and the lateral deformation of specimens were recorded. As well as, the failure forms of specimens were observed after the impact tests. A common hollow reinforced concrete specimen was selected and compared with the hollow reinforced concrete column with inner octagon steel tube under the same conditions. The results show that the impact resistance of the hollow reinforced concrete columns with inner octagon steel tube is obviously better than that of the corresponding hollow reinforced concrete columns by using the inner steel tube instead of the built-in steel cage. Within the range of axial compression ratio not exceeding 0.3, the change of axial compression ratio has little effect on the residual deflection of hollow reinforced concrete columns with inner octagon steel tube after impact.
