Notes:

  1. The Load Span Table above is based on Allowable Stress Design (ASD). For loads calculated based on ASCE 7-10 (LRFD), please refer to section 2.4.1 of ASCE 7-10 for the applicable load combinations using Allowable Stress Design.
  2. Based on CF-42 panel with 26 ga. Light Mesa exterior and 26 ga. Light Mesa interior face (min Fy = 33 ksi).
  3. Fastener pattern FP1 is based on CF panel clips fastened to min. 14 ga. steel. Fastener options will be (2) ¼” -14 SDS Type 3, (2) ¼” -14 Self-Tapping, (2) ¼” -14 Type 5 SDS, (2) ¼” -20 Type 5 SDS, or (2) ¼” -28 Type 5 SDS. Fastener selection will be based on fastener pullout capacity from support steel members.

Fastener shall be of sufficient length to penetrate through the support a minimum of 3/4″. Fastener selection will be based on fastener pullout capacity from support steel members.
  7. Allowable positive or suction load is the lowest value of panel bending strength, shear strength, deflection limit and connection strength for each fastener pattern.
  8. Allowable loads based on panel stress and deflection design criteria are derived from ASTM E72 structural testing and
    calculated with factor of safety of 2.5 for bending stress, 3.0 for shear stresses and deflection limitation of L/180.
  9. The panel connection strength was determined from ASTM E1592 testing and the allowable loads are calculated with factor of safety of 2.
  10. The structural capacity of the purlins are not considered and must be examined independently.

  2. Allowable span is the lowest value of panel bending strength, shear strength and deflection limit.
  3. The spans based on panel stress and deflection design criteria are derived from E-72 structural testing. The allowable loads are calculated with a factor of safety of 2.0 and 3.0 for bending and shear stresses, respectively and deflection limitation of L/120.
  4. The structural capacity of support members and panel attachment to the support members are not considered and must be examined independently.

IMPORTANT NOTES:

Deflection caused by temperature differential induced thermal bow is not addressed in the above table and may result in allowable spans that are less than the spans listed above and may require the use of heavier 24 or 22 gage panel facings at added cost. Except for self-supporting the dead weight of the panel, partition wall panels are non-load bearing. Ceiling panels must be supported from the structure above or by an internal support structure.  Panel skins must be captured at both ends of the panel by supporting members designed to support reaction pressures from a 5 psf interior pressure. CF-42 = 42″ wide. CF-45 = 44.5″ wide.
