No letter next to the number means deflection controls. Notes: 1. Limiting heights are in accordance with AISI S100-07 using all steel non-composite design. 2. Limiting heights are established by considering flexure, shear, web crippling and deflection. 3. For bending, studs are assumed to be adaquately braced to develop full allowable moment. Studs are considered fully braced when unbraced length is less than Lu. See section properties table on page 5 for Lu values. 4. For web crippling, when h/t ≤ 200, the web crippling values are computed based on section C3.4.2 of AISI S100-07, when h/t >200, the web crippling values are based on testing with a bearing length of 1". 5. No web stiffeners are required for studs with h/t > 200, web crippling and shear values have been confirmed by testing. 6. The factory punchouts are in accordance with section C5 of AISI S201-07. The distance from the center of last punchout to the end of the stud is 12". 8 L/120 6'-7" f --8'-10" f 7'-8" f -10'-4" f 9'-0" f 6'-7" w 10'-7" f 9'-2" f 6'-5" w 10'-7" w 7'-11" w -8'-8" 7'-8"f 6'-4" f 11'-8" f 10'-1" f 8'-4" f 13'-10" f 11'-11" f 9'-8" f 15'-8" f 13'-7" f 11'-1" f 18'-5" f 15'-11" f 12'-1"w 9'-4" 8'-1" f 6'-7" f 12'-5" f 10'-8" f 8'-10" f 15'-0" f 13'-0" f 10'-7" f 15'-11" f 13'-8" f 11'-2" f 19'-11" f 17'-2" f 12'-5" w 9'-7" 8'-8" f 7'-1" f 13'-4" f 11'-6" f 9'-5" f 16'-4" f 14'-1" f 11'-6" f 17'-2" f 14'-11" f 12'-1" f 21'-6" f 18'-7" f 15'-2" f 10 PSF L/240 6'-0" --8'-5" 7'-7" -10'-4" f 9'-0" f 6'-7" w 10'-7" f 9'-2" f 6'-5" w 10'-7" w 7'-11" w -6'-11" 6'-4" -9'-6" 8'-7" 7'-6" 12'-6" 11'-5" 9'-8" f 13'-6" 12'-4" 10'-8" 17'-11" 15'-11" f 12'-1"w 7'-5" 6'-8" -10'-2" 9'-4" 8'-1" 13'-7" 12'-5" 10'-7" f 14'-8" 13'-5" 11'-2" f 19'-11" f 17'-2" f 12'-5" w 7'-7" 6'-11" 6'-1" 10'-7" 9'-7" 8'-5" 14'-1" 12'-10" 11'-2" 15'-2" 13'-10" 12'-1" 20'-11" 18'-7" f 15'-2" f L/360 ---7'-4" 6'-8" -9'-7" 8'-10" 6-7" w 10'-5" 9'-2"f 6'-5"w 10'-7"w 7'-11"w -6'-0" --8'-4" 7'-6" 6'-7" 10'-11" 9'-11" 8'-8" 11'-10" 10'-8" 9'-5" 15'-7" 14'-2" 12'-1"w 6'-6" --8'-11" 8'-1" 7'-1" 11'-11" 10'-10" 9'-5" 12'-11" 11'-8" 10'-2" 17'-6" 15'-11" 12'-5"w 6'-8" 6'-1" -9'-2" 8'-5" 7'-4" 12'-4" 11'-2" 9'-10" 13'-4" 12'-1" 10'-7" 18'-2" 16'-7" 14'-6"
