Notes:
• Calculated properties are based on AISI S100-12, North American Specification for Design of Cold-Formed Steel Structural Members and AISI S220-15, 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 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.
