(a) For No. 5 bar and D31 wire, and smaller, and for No. 6 through No. 8 bars with fyt ≤ 40,000 psi, a standard hook around longitudinal reinforcement
(b) For No. 6 through No. 8 bars with fyt > 40,000 psi, a standard hook around a longitudinal bar plus an embedment between midheight of the member and the outside end of the hook equal to or greater than , with λ as given in Table 188.8.131.52
(c) In joist construction, for No. 4 bar and D20 wire and smaller, a standard hook
(a) Two longitudinal wires spaced at a 2 in. spacing along the member at the top of the U
(b) One longitudinal wire located not more than d/4 from the compression face and a second wire closer to the compression face and spaced not less than 2 in. from the first wire. The second wire shall be permitted to be located on the stirrup leg beyond a bend, or on a bend with an inside diameter of bend of at least 8db.
(a) Inner longitudinal wire at least the greater of d/4 or 2 in. from d/2
(b) Outer longitudinal wire at tension face shall not be farther from the face than the portion of primary flexural reinforcement closest to the face
(a) Ends shall terminate with 135-degree standard hooks around a longitudinal bar
