23.6.1
Compression reinforcement in struts shall be parallel to the axis of the strut and enclosed along the length of the strut by closed ties in accordance with 23.6.3 or by spirals in accordance with 23.6.4.
23.6.2
Compression reinforcement in struts shall be anchored to develop fs' at the face of the nodal zone, where fs' is calculated in accordance with 23.4.1.
23.6.3
Closed ties enclosing compression reinforcement in struts shall satisfy 25.7.2 and this section.
23.6.3.1
Spacing of closed ties, s, along the length of the strut shall not exceed the smallest of (a) through (c):
(a) Smallest dimension of cross section of strut
(b) 48db of bar or wire used for closed tie reinforcement
(c) 16db of compression reinforcement
23.6.3.2
The first closed tie shall be located not more than 0.5s from the face of the nodal zone at each end of a strut.
23.6.3.3
Closed ties shall be arranged such that every corner and alternate longitudinal bar shall have lateral support provided by crossties or the corner of a tie with an included angle of not more than 135 degrees and no longitudinal bar shall be farther than 6 in. clear on each side along the tie from such a laterally supported bar.
23.6.4
Spirals enclosing compression reinforcement in struts shall satisfy 25.7.3.
