Dynamic Response of RPC-filled Steel Tubular Columns Under Axial Impact Loading

DU Xiu-li

Abstract

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.
