ℓn is the clear span in the long direction, measured face-to-face of supports (in.).
For fy between the values given in the table, minimum thickness shall be calculated by linear interpolation.
Slabs with beams between columns along exterior edges. Exterior panels shall be considered to be without edge beams if αf is less than 0.8. The value of αf for the edge beam shall be calculated in accordance with 184.108.40.206.

ℓn is the clear span in the long direction, measured face-to-face of beams (in.).
β is the ratio of clear spans in long to short directions of slab.
(a) Nonprestressed slabs not satisfying 8.3.1
(b) Nonprestressed slabs without interior beams spanning between the supports on all sides and having a ratio of long-to-short span exceeding 2.0
(c) Prestressed slabs
