Notes: 1. Web height to thickness ratio (h/t) exceeds 200. Web
stiffeners required at all support points and concentrated loads.
2. Members having a web height to thickness ratio (h/t) value
exceeding 260 will not have effective properties listed, only grossproperties will be listed. 3. Web height value (h) used for h/t

calculation is the flat width of the web. For (S) members, this is theout to out member size, minus twice the thickness, minus twice theinside bend radius. 4. Members having a flange width to thickness
ratio (b/t) value exceeding 60 must be considered for use with thelimitations described in AISI S100 & S220 section B1. 5. FlangeJ(x 10-6)(in4)

width value (b) used for b/t calculation is the flat width of the flange.
For (S) members, this is the out to out member size, minus twice thethickness, minus twice the inside bend radius.

Notes: 1. Web height to thickness ratio (h/t) exceeds 200. Web
stiffeners required at all support points and concentrated loads.
2. Lateral loads of 5 psf, 7.5 psf, and 10 psf have NOT been reduced
for strength or deflection checks. Full lateral load is applied.
3. Limiting heights are in accordance with AISI S100 & S220 using

all steel non-composite design. 4. Limiting heights are establishedby considering flexure (f), web crippling (w) and deflection. 5.
Allowable moment is the lesser of Mal and Mad. Stud distortional
buckling based on an assumed KΦ = 0. 6. For bending, studs are
assumed to be adequately braced to develop full allowable moment.

7. Web crippling check is based on AISI S100 & S220 section C3.4.2
Condition 1: End One-Flange Loading with 1” end bearing.

are established by considering flexure, shear, web crippling, and deflection. 3. Mechanical fastening of gypsum panel to the stud andtrack is required, except when installing a minimum 30 mil slotted

track with 2-1/2” legs in lieu of standard track. 4. Viper-X composite limiting heights based on a single layer of 5/8” type X gypsum
board applied vertically to both sides of the wall over full height. 5/8”
Type X wallboard from the following manufacturers are acceptable:
USG, National, Georgia-Pacific, PABCO, CertainTeed, & American.

Notes: 1. Shear values are tested per AISI S100, S220 & S905 procedure. 2. Capacities are based on section E4 of the AISI S100 &S220 Specification. 3. Capacities are based on Allowable Strength
Design (ASD). 4. Screw pull-out capacities are based on listed headdiameter. 5. Two sheets of equal thickness and tensile strength areassumed in tabulated values. 6. When materials of different steel

thickness and tensile strength are connected, use the lowest value
for shear capacity (tilting and bearing), for pull-out capacity use sheet
closest to screw tip and for pull-over capacity use sheet closest
to screw head. 7. Where multiple fasteners are used, screws areassumed to have a center-to-center spacing of at least 3 times thenominal diameter. 8. Screws are assumed to have a center-of-screw
