Abstract:
A reexamination of the blast effects literature from the point of view of fragmentation leads to the conclusion that reinforced concrete slabs do not constitute a significant source of debris in the postattack environment. Both the initial orientation and the self-adjusting geometry of slabs minimize their transverse loading. Also, the horizontal displacement of potential slab fragments tends to be small because of their high ballistic coefficients andor high downward acting loading. Finally, the steel reinforcing bars tenaciously tie the various pieces of fractured slab to the supports and to each other even at pressure levels as high as 100 psi.
