Research on Reinforced Concrete Column under High Speed Impact of Different Diameter Projectile

In order to study the dynamic response of the reinforced concrete column which is under the high speed impact of different diameter projectile, LS-DYNA finite element calculation software was used to, designing four kinds of solutions, calculate and analyse the reinforced concrete column under the situations. Projectile velocity curve、projectile acceleration curve and the results of reinforced concrete column damage of different α value(the ratio of projectile diameter and reinforced concrete column side length) in the conditions of the same impact parts(1/2 of the column high) and initial velocity(800m/s)were obtained. Based on the analysis of the numerical simulation results, we get the influence rule of the dynamic response of reinforced concrete column which is under the impact of different diameter projectile.
