Notes:
– Calculated properties are based on AISI S100-07, North American Specification for Design of Cold-Formed Steel Structural Members and AISI S220-11, North American Standard for
Cold-Formed Steel Framing—Nonstructural Members.
– Effective properties incorporate the strength increase from the cold work of forming as applicable per AISI A7.2.
– Tabulated gross properties, including torsional properties, are based on full-unreduced cross section of the studs, away from punchouts.
– Tabulated gross properties, including torsional properties, are based on full-unreduced cross section of the tracks.
– For deflection calculations, use the effective moment of inertia.
– Allowable moment includes cold work of forming.
– Allowable moment is taken as the lowest value based on local or distortional buckling. Distortional buckling strength is based on a k-phi = 0.
– Web depth for track sections is equal to the nominal height plus two times the design thickness plus the bend radius. Hems on nonstructural track sections are ignored.
1 Web-height to thickness ratio exceeds 200. Web stiffeners are required at bearing points.
2 Web-height to thickness ratio exceeds 260. Web stiffeners are required at bearing and intermediate points.
