EFFECT OF REINFORCEMENT RATIO ON THE RESISTANCE OF REINFORCED-CONCRETE TO HARD PROJECTILE IMPACT

This paper discusses the effect of the reinforcement ratio on the perf oration resistance of reinforced concrete elements, and proposes a way to evaluate it quantitatively. A review of the works that refer to th e reinforcement effect on the perforation resistance, is followed by a theoretical quantitative evaluation of this effect. This theoretical expression is then used to modify existing perforation formulae, such that they include the reinforcement ratio as a variable. The theoretic al results are compared to experimental results of tests that were pla ned to observe the resistance of concrete plates with different reinfo rcement ratios, to hard projectile impact.
