*d*_{b}**beyond the point where bent or terminated tension reinforcement is no longer required to resist flexure.**

*ℓ*_{d}(a) ** V_{u} ≤ (2/3)ϕV_{n}** 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 ** V_{u} ≤ (3/4)ϕV_{n}**.

(c) Stirrup area in excess of that required for shear is provided along each terminated bar or wire over a distance **3/4 d** from the termination point. Excess stirrup area shall be not less than

**60**. Spacing

*d*/(8β_{b})**for positive moment tension reinforcement shall be limited such that**

*d*_{b}**for that reinforcement satisfies (a) or (b). If reinforcement terminates beyond the centerline of supports by a standard hook or a mechanical anchorage at least equivalent to a standard hook, (a) or (b) need not be satisfied.**

*ℓ*_{d}(a) ** ℓ_{d} ≤ (1.3M_{n}/V_{u} + ℓ_{a})** if end of reinforcement is confined by a compressive reaction

(b) ** ℓ_{d} ≤ (M_{n}/V_{u} + ℓ_{a})** if end of reinforcement is not confined by a compressive reaction

** M_{n}** is calculated assuming all reinforcement at the section is stressed to

*f*_{y}**is calculated at the section. At a support,**

*V*_{u}**is the embedment length beyond the center of the support. At a point of inflection,**

*ℓ*_{a}**is the embedment length beyond the point of inflection, limited to the greater of**
