Home > Section properties


  • Section properties and capacities are calculated in accordance with AISI-NASPEC 2001 with 2004 Supplement.
  • Tabulated gross properties are based on the full, unreduced cross section of the stud away from punchouts.
  • Effective section properties incorporate the strength increase from cold work of forming as applicable per AISI-NASPEC, Sec. A7.2.
  • Net effective section properties are calculated at a cross section through the punchout.
  • For deflection calculations, use the effective moment of inertia (Ix). This Ix is calculated at a stress 0.6 Fy (service load level).
