Use #5 stirrups except as noted, with a 4 in. minimum and a 12 in. maximum spacing. Do not use stirrups larger than #6. Use double stirrups if required spacing is less than 4 in. If torsional resistance is explicitly addressed in the design, ensure the stirrup detailing is consistent with AASHTO requirements.

For flexural reinforcement, use #11 bars. Smaller bars can be used to satisfy development requirements. Do not mix bar sizes.

Use longitudinal skin reinforcement in accordance with Equation 5.6.7-3 in caps deeper than 3 ft. Caps 3 ft. and less should have two #5 bars, as a minimum, equally spaced in each side face.
