Diaphragm Design Limits per ACI 318-19 with ideCAD
How does ideCAD control diaphragm design limits according to ACI 318-19?
The minimum diaphragm thickness is controlled and reported automatically according to Table 8.3.1.1 for flat slabs.
The minimum diaphragm thickness is controlled and reported automatically according to Table 8.3.1.2 for beam-to-slabs.
Symbols
h = overall thickness, height, or depth of member, in.
ln = length of clear span measured face-to-face of supports, in.
fy = specified yield strength for nonprestressed reinforcement, psi
αfm = average value of αf for all beams on edges of a panel
Minimum diaphragm thickness
There are two different slab thickness limits according to flat slab and beam-to-slab. According to 12.3.1.2, floor and roof diaphragms are controlled automatically in accordance with their slab type.
