| Abstract: Buried civilian shelters that designed against missile effect, require existence of concrete layer on the ground level at a certain distance above the buried shelter. This layer should be strong and thick enough to resist missi le penetration. In this paper, the effect of backfill soil type on concrete penetration resistance was studied. Damage level due to different impact velocities was also evaluated according to crater dimensions at front and back face of concrete targets. The study showed that using sand as a backfill improved penetration resistance more than using gravel. The study also prevailed the importance of front face reinforcement with increasing target thickness. It was also found that damage level in perforated targets increased with increasing target thickness. | ||||
