Steel Strong-Wall® : Cold-Formed Steel on Concrete Foundations

S/SSW12x8X and S/SSW24x10X
S/SSW12X and S/SSW24X

Patent Pending

The Steel Strong-Wall provides high-capacity, narrow wall solutions for cold-formed steel framing. The wall installs easily in cold-formed steel framing, and pre-attached steel studs allow easy attachment of interior and exterior finishes.

  • For top-of-wall attachment, use 1/4" or #14 self-drilling screws (not provided) extended through the connection with 3 exposed threads minimum. Fill all screw holes
  • Maximum height H is the maximum height allowed for the allowable shear loads.

For SI: 1 inch = 25.4 mm, 1 foot = 305 mm, 1 lb = 4.45 N.

  1. Allowable shear loads and anchor uplifts are applicable to installation on concrete with minimum specified compressive strength f'c = 2,500 psi. No stress increases are included.
  2. The axial load denotes the total maximum uniformly distributed vertical downward load permitted on the entire panel acting in combination with the shear load. No stress increases are included.
  3. Top of panel must be connected with screws described in Table 2 of this report to a minimum 43 mil thick steel member except S/SSW18 and wider panels up to 97 inches tall must be connected to a minimum 54 mil thick steel member. When connected to a minimum 43 mil thick steel member, the maximum allowable load must be 2,720 pounds for S/SSW18, 3,625 pounds for S/SSW21, and 4,230 pounds for S/SSW24.
  4. Allowable shear, drift, and uplift values may be interpolated for intermediate height or axial loads.
  5. High strength anchor bolts are required unless a lower strength grade is justified by the registered design professional. Anchor bolts for the SSW12 shall be high strength when seismic shear (V) x panel height exceeds 61,600 in-lbs. Figure 7 of this report provides SSWAB anchor bolt information and anchorage solutions.
  6. Tabulated anchor tension (uplift) loads assume no resisting axial load. For anchor tension loads at design shear values and including the effect of axial load, refer to the equations in Figure 8 of this report. Drifts at lower design shear may be linearly reduced.
  7. Table 11 of this report describes allowable out-of-plane loads and Table 12 of this report describes allowable axial capacities.
  8. The available strength, Rn/Ω, for CFS collector element (top track or header) design within a seismic force-resisting system shall be greater than or equal to PULT
