NOTES

  1. All calculations for the properties of panels are calculated in accordance with the 1986 edition of Specifications for the Design of Light Gauge Cold Formed Steel Structural Members - published by the American Iron and Steel Institute (A.I.S.I.).

  2. Ix is for deflection determination.

  3. Sx is for bending.

  4. Ma is allowable bending moment.

  5. All values are for one foot of panel width.

NOTES

  1. Allowable loads are based on uniform span lengths and Fy of 80 KSI for 29 and 26 gauge and Fy of 50 KSI for 24 and 22 gauge.
  2. Live load is allowable live load.
  3. Wind load is allowable wind load and has been increased by 33.333%.
  4. Deflection loads are limited by a maximum deflection ratio of L/240 of span or maximum bending stress from live load.
  5. Weight of the panel has not been deducted from allowable loads.
  6. Load table values do not include web crippling requirements or connection of panel to substrate.
  7. Minimum bearing length of 1.5 required.
  8. See pages 19-20 for minimum fastener pattern.
