When a reinforced concrete element is dynamically loaded, the element deflects until such time that: (1) the strain energy of the element is developed sufficiently to balancethe kinetic energy produced by the blast load and the element comes to rest, or (2)fragmentation of the concrete occurs resulting in either partial or total collapse of theelement. The maximum deflection attainable is a function of the span of the element,the depth of the element, and the type, amount, and details of the reinforcement used ina particular design.
