Notes:

  1. Allowable loads are based on uniform span lengths and Fy = 60 ksi.
  2. Live Load is limited by bending, shear, combined shear & bending and web crippling.
  3. Negative Wind Load does not contain a 33.333% increase and does not consider fastener pullout or pullover.
  4. Above loads consider a maximum deflection rate of L/180.
  5. The weight of the panel has not been deducted from the allowable loads.
  6. The use of any accessories other than those provided by the manufacturer may damage panels, void all warranties and will void all engineering data.
  7. This material is subject to change without notice.  Please contact Metl-Span for most current data.

*Panels are made from 80 ksi yield material. Flexural effective yield strengths vary by direction of bending. Shear and web crippling capacities have been determined using an effective yield strength of 60 ksi.

Ixe = effective moment of inertia per foot of panel width at nominal moment capacity.
Sxe = effective section modulus per foot of panel width at nominal moment capacity.
Maxo = allowable bending moment base on initiation of yielding.
