ENGINEERING PROPERTIES FOR DOUBLE-LOK® STEEL PANELS
1. All calculations for the properties of Double-Lok® panels are calculated in accordance with the 2001 edition of the COLD-FORMED STEEL Design Manual – published by the American Iron and Steel Institute (AISI).
2. Ixe is for de ection determination.
3. Sxe is for bending.
4. Maxo is allowable bending moment.
5. All values are for one foot of panel width.
6.Please inquire for Ultra-Dek® Engineering Properties.
ALLOWABLE UNIFORM LOADS IN POUNDS PER SQUARE FOOT
1. Allowable loads are based on uniform span lengths and panel yield strength (Fy) = 50 ksi.
2. LIVE LOAD is limited by bending, shear and combined shear & bending. 3. Above loads consider a maximum de ection ratio of L/180.
4. THE ABOVE LOADS ARE NOT FOR USE WHEN DESIGNING PANELS TO REDUCE WIND UPLIFT.
5. Weight of the panel has not been deducted from allowable loads.
6. Please contact manufacturer or manufacturer’s website for most current allowable wind uplift loads.
7. The use of any eld seaming machine other than that provided by the manufacturer may damage the panels, void all warranties and will void all engineering data.
