Abstract
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.
