7.7.3 Flexural Reinforcement in Nonprestressed Slabs
(a) Vu ≤ (2/3)ϕVn at the cutoff point.
(b) For No. 11 bars and smaller, continuing reinforcement provides double the area required for flexure at the cutoff point and Vu ≤ (3/4)ϕVn.
(c) Stirrup area in excess of that required for shear is provided along each terminated bar or wire over a distance 3/4d from the termination point. Excess stirrup area shall be not less than 60bws/fyt. Spacing s shall not exceed d/(8βb).
(a) ℓd ≤ (1.3Mn/Vu + ℓa) if end of reinforcement is confined by a compressive reaction
(b) ℓd ≤ (Mn/Vu + ℓa) if end of reinforcement is not confined by a compressive reaction
Mn is calculated assuming all reinforcement at the section is stressed to fy and Vu is calculated at the section. At a support, ℓa is the embedment length beyond the center of the support. At a point of inflection, ℓa is the embedment length beyond the point of inflection, limited to the greater of d and 12db.
