Load Tables

VGT/SVGT
  1. Designer shall insure attached members are adequately designed to resist applied loads.
  2. Straight-line interpolation can be used to determine allowable loads for pitches between 3/12 and 8/12.
  3. Allowable loads on wood have been increased 60% for wind or earthquake loading with no further increase allowed; reduce where other load duration factors govern.
  4. For (min.) tabulated values, not all screw holes need to be filled. Install screws symmetrically.
  5. See Fastening Systems for more information on Simpson Strong-Tie fasteners.
