Title: Effect of slab flexural reinforcement and depth on punching strength
Author(s): Neil M. Hawkins, Carlos E. Ospina
Publication: Special Publication
Appears on pages(s): 117-140
Keywords: Concrete design codes, depth effect, flat slabs, moment transfer, punching shear, reinforcement ratio, size effect, slab-column connections
Abstract:Recommendations are presented for proposed revisions to the punching shear provisions of ACI 318-14 in order to recognize the limitations imposed on punching shear capacity by low amounts of slab flexural reinforcement and by slab depth effects. The influence of those two factors is investigated by examining relevant experimental results from tests on slab-column assemblages and slab systems.
