Abstract:
Concrete has been widely used over many years by military and civil engineers in the
design and construction of protective structures. One of the loading types that protective
structures are designed to withstand, is the localized impact of missiles or projectiles.
Parameters that affecting design process are the barrier or target geometry (mainly thickness),
and concrete properties. In this paper, the effect of dividing concrete target on perforation
resistance was studied through 23 specimens (37 concrete panels) with total different
thicknesses (10, 15 and 60 cm). The thickness of the part of the divided target that faces the
impacting missile was also studied. The study showed that dividing concrete target ha d
positive effect on perforation resist ance provided that the biggest divided mass faces the
impact missile.
