中文摘要：

采用一级轻气炮驱动飞片撞击实验技术,对3种不同配筋率下的钢筋混凝土靶板进行了动力冲击压缩实验,测得不同冲击速度下的应力-时程曲线.通过Lagrange分析方法对实验数据进行处理,分析了配筋及配筋率对材料性能的影响.结果表明：在强冲击载荷作用下,配筋率的增加提高了整体的抗冲击性能;钢筋的加入在一定程度上降低了混凝土材料的刚度和强度.

英文摘要：

Dynamic compressive tests were conducted using light gas gun induced-plate impact experiment technology with three different reinforcement ratios. Stress histories were obtained at different impact velocities. Lagrange analysis was used to calculate the strain and specific internal energy history of reinforced concrete. Influence of reinforcement and reinforcement ratio on the concrete is analyzed. The experimental results showed that there was no improvement of dynamic compressive behavior of concrete by adding reinforcing steel webs in the range of reinforced ratio in the experiments. However, the dynamic compressive strength and ductibility of the reinforced concrete increased greatly when the reinforce ratio increased. Thus the dynamic behavior of reinforced concrete was greatly influenced by the reinforcement of steel and the increase of initial damage by introducing steel webs to the concrete.
