Notes: 1) Theoretical section properties computed for flexural loads per AISI Cold Formed Steel Design Manual 1986 Edition. 2) Loads in tables based on continuous beam over three equal spans. For stress loads, 2-span load would be 0.80 of the 3-span load. 3) Allowable loads have not been increased by 33 1/3% for wind uplift. 4) Allowable loads for deflection based on deflection limitation of span/180. 5) For roof panels, self weight of the panel has to be deducted from the allowable inward load to arrive at the actual “live load” carrying capacity of the panel.
