Dynamic punching shear of impacting RC flat slabs with drop panels

Reinforced concrete flat slabs (FS) are sensitive to punching shear failure. Such failure may progress to the slab loss of supports and its downwards motion that is followed by its impact with the slab underneath. This slabs impact may initiate a progressive collapse of the entire building. The design guidelines provided by modern standards to avoid punching shear failure and to prevent post-punching loss of slab support in an attempt to prevent...
