- Multiply value by (12/d) 1/9 where d=depth of member
- Multiply value by (4/L) 1/8 where L=4 ft. for members 4 ft and less. L=member length in ft. for members longer than 4 ft.
- Design values are based on 100% duration of load. Increases of stresses are permitted for all values except compression perpendicular to grain.
- This value cannot be increased for duration of load.
- The design stress are applicable to material used in dry service conditions where the maximum moisture content of the wood will not exceed 12.5 percent.
- Bolt and nail values are as provided in 1991 National Design Specification for Douglas Fir-Larch, G=0.50.
