is no foolproof method of guaranteeing perfect safety from mortar
attack. Our mortar defense structures provide a viable solution to the
problem. A building mortar bomb defence will be improved with
Defence-Structures mortar roofs consisting
a) A yielding steel grillage mounted on yielding
steel supports on a stand off above the roof. This will catch, disrupt
or detonate mortar bombs.
b) A reinforced concrete deck built onto composite
style steel decking. This will stop penetration of small fragments.
Larger more energetic fragments, though they may pulverise the concrete
and bulge or even penetrate the steel decking, will have lost most of
their energy. The concrete deck is supported by steel frames.
c) A standoff below the concrete deck to the
normal roof of the building designed for climatic protection but
probably able to stop any remaining fragments.
d) Where large calibre anti tank rockets are being
used as mortars, but on a medium trajectory instead of high, the
defence structures mortar roof may need additional bracing against the
horizontal kinetic energy of the projectiles.
