Notes:

Footnote 1

The specified design stresses in Table 4.1.1 are for standard term load duration and must be adjusted (with the exception of modulus of elasticity) using load duration factors as per CAN/CSA-O86-14.

Return to footnote 1 referrer

Footnote 2

The specified design stresses in Table 4.1.1 apply to product installation conditions that are dry, well ventilated and covered. Dry conditions are product installation conditions where ambient moisture content is 15% or less.

Return to footnote 2 referrer

Footnote 3

All specified strengths are in accordance with CAN/CSA-O86-14.

Footnote 4

The specified bending strength, Fb, is assigned for a standard depth of 305 mm (12 in.). For other product depths, multiply Fb as follows:

For 2580F_b − 1. 55E_apparent (1.6E_shear-free): multiply F_b by (305/depth in mm)^0.25 [(12/depth in in.)^0.25]. For depths < 89 mm (3½ in.), use value for 89 mm.
For 2700F_b − 1. 8E_apparent (1.9E_shear-free): multiply F_b by (305/depth in mm)^0.16 [(12/depth in in.)^0.16]. For depths < 89 mm (3½ in.), use value for 89 mm.
For 3000F_b − 1. 9E_apparent (2.0E_shear-free): multiply F_b by (305/depth in mm)^0.16 [(12/depth in in.)^0.16]. For depths < 89 mm (3½ in.), use value for 89 mm.
For 3100F_b − 2.0E_apparent (2.1E_shear-free): multiply F_b by (305/depth in mm)^0.15 [(12/depth in in.)^0.15]. For depths < 89 mm (3½ in.), use value for 89 mm.

Footnote 5

The specified tension strength, F_t, is assigned for a standard length of 6 096 mm (20 ft.). For lengths greater than 6 096 mm (20 ft.), multiply F_t by (6 096/length in mm)^0.146 [(20/length in ft.)^0.146].

Footnote 6

Joist orientation is LVL on edge with load parallel to the glue line. Plank orientation is LVL on the flat, with the load perpendicular to the glue line. Axial is tension or compression along the length of the member.

Return to footnote 6 referrer

Footnote 7

When using the shear-free modulus of elasticity, E_shear-free, the total deflection of a simply supported beam subjected to uniform loads can be calculated as follows:

$Δ = \frac{156 W L^{4} \times 10^{6}}{E_{shear-free} b d^{3}} + \frac{2400 W L^{2}}{E_{shear-free} b d}$

Where:

D = deflection, mm

W = specified uniform load, N/m

L = span, m

E_shear-free = shear-free modulus of elasticity, MPa

b = beam width, mm

d = beam depth, mm
