Notes:

Footnote 1

All values are in accordance with CSA O86.

Footnote 2

Specified strengths are for standard term load duration and may be adjusted (with the exception of modulus of elasticity [MOE]) using load duration factors in accordance with CSA O86.

Return to footnote 2 referrer

Footnote 3

Specified bending stresses must apply to product installation conditions of use that are dry, well-ventilated interior applications in which the equivalent MC of lumber would not exceed 15%.

Return to footnote 3 referrer

Footnote 4

The specified strengths for "Beam" refer to loads applied parallel to the wide face of the strands (the edge of the member). "Plank" refers to loads applied perpendicular to the wide face of the strands (the face of the member). See Figure 2 for loading direction with respect to strand orientation.

Return to footnote 4 referrer

Footnote 5

The MOE is shear-free; therefore, when calculating deflection, both bending and shear deformations must be included. The following equation may be used for a simple supported loading condition under uniform load:

$Δ = \frac{5 w L^{4}}{384 E I} + \frac{2.4 w L^{2}}{E b d}$

where:

Δ = deflection (mm)

w = specified uniform load (N/mm)

L = span (mm)

E = modulus of elasticity (shear-free) (MPa)

I = moment of inertia (mm4)

b = beam width (mm)

d = beam depth (mm)

Return to footnote 5 referrer

Footnote 6

The specified "Beam" bending strength, Fb, is based on a standard depth of 305 mm. For other depths, multiply the values of F_b by (305/d)^0.120 (where d is in mm). For depths less than 69 mm, multiply F_b by 1.159.

Return to footnote 6 referrer

Footnote 7

The plank compression perpendicular to grain is based on the lesser of the average proportional limit stress and the average stress at the 1 mm (0.04 in.) deformation. In the calculation of the compressive resistance perpendicular to grain K_Zcp must be 1.0 for the plank orientation (L-X).

Return to footnote 7 referrer

Footnote 8

The specified tension strength, Ft, is assigned for a standard length of 6 096 mm (20 ft.). For other lengths, multiply Ft by (6 096/L)^0.092 (where L is in mm). For lengths less than 914 mm, use the design tensile stresses adjusted to 914 mm.

The factored resistances are for the rim board only, under standard term and dry service loading; therefore, adjustment is permitted for other load durations in accordance with CAN/CSA-O86-14, "Engineering Design in Wood." The compressive resistance of the sill plate also must be checked in accordance with CAN/CSA-O86-14.
