About this detail

Standard reinforcing bar hook configurations, bend diameters, and extension lengths are detailed for structural concrete stirrups and ties. Standard hooks feature 90-degree and 135-degree bends with extension lengths specified as four bar diameters for sizes #3 through #5, and six bar diameters for sizes #6 through #8. Closed ties, beam stirrups, cross ties, and circular ties show alternating ninety-degree and one-hundred-thirty-five-degree hook placements. Overlaps at adjacent circular ties are staggered with a six-inch minimum spacing.
