摘　　要：基于Hopkinson压杆冲击试验和数值模拟分析,研究了钢管RPC构件对高应变速率冲击荷载的动力响应规律,获得了这种构件的承载力提高系数及构件中钢管与RPC芯柱对冲击动荷载的分配比例关系.Because of good impact toughness and high load carrying capacity,RPC-filled steel tubular columns promise to be good blast-resistant and impact-resistant structural members.Experimental investigation for impact-resistant property of RPC-filled steel tubular columns is conducted in this paper.Dynamic response of the columns under axial impact loading is studied by means of numerical simulation method.Increase coefficient of load carrying capacity and ratio of load carrying capacity of steel tube to that of RPC core in the columns are obtained.

关 键 词：钢管RPC 冲击试验 数值模拟 承载力提高系数 荷载分配比
