Load Tables
- Designer shall insure attached members are adequately designed to resist applied loads.
- Straight-line interpolation can be used to determine allowable loads for pitches between 3/12 and 8/12.
- 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.
- For (min.) tabulated values, not all screw holes need to be filled. Install screws symmetrically.
