FOOTNOTES FOR TABLES 7 AND 8
  1. The 20 psf non-snow live loads have been reduced to 16 psf for slopes of 4:12 and greater. Reduce spans 3'-0" for Joists slopes greater than 8:12. Maximum roof slope Is 12:12.
  2. Spans shown are simple horizontal clear spans.
  3. Maximum deflection Is limited to L/180 under total load, and L/240 under live load.
  4. Spans are based on 1-3/4' exterior reactions without web stiffeners.
