摘　　要：对16根钢管混凝土短柱进行了轴向冲击试验研究。通过试验证明:在冲击荷载作用下,钢管混凝土结构具有很高的承载能力和塑性变形能力,是一种理想的抗冲击结构材料。在试验的基础上利用有限元分析软件ANSYS模拟,通过模拟结果与试验结果的比较,得出了钢管混凝土短柱轴向冲击作用下的一些动力特性。The 16 steel tube-confined concrete short columns are selected and their dynamic response under axial impact load are studied. Through comparing the test result, it can be proofed that the steel tube-confined concrete structure has very high bearing capacity and plastic deformation ability under impact load, so it is a kind of ideal structural material to bear impact. On the foundation of test, it is simulated using the finite element software ANSYS, Through comparing the test result and the simulated result, the dynamic resnonse of it is summarized.
