Notes:

Footnote 1

All specified strengths are based on CSA O86-14 (Update No. 1). Standard term K_D = 1.0. Dry service use K_S = 1.0.

Footnote 2

For depths greater than or equal to 44 mm, multiply by (305/d)^1/5; for depths less than 44 mm, multiply by 1.47, where d = depth in joist orientation (mm).

Footnote 3

For depths greater than or equal to 44 mm, multiply by (44/d)^1/3; for depths less than 44 mm, multiply by 1.00, where d = depth in plank orientation (mm).

Footnote 4

Tension values are adjusted to a reference length of 6 096 mm. For lengths greater than or equal to 1 219 mm, multiply by (6 096/L)^1/10; for lengths less than 1 219 mm, multiply by 1.17, where L = length in mm.
