Notes:

Footnote 1

DF = Douglas Fir-Larch, LP = Lodgepole Pine, SP = Southern Pine (may contain no more than 50% of Red Maple) and YP = Yellow Poplar (may contain no more than 50% of Red Maple). DF and LP can be combined as Western Species (WS). SP and YP can be combined as Eastern Species (ES). Red Maple is limited to 50 percent of the plies in a pattern that otherwise consists of Southern Pine or Yellow Poplar veneer and the plies shall not be used as face sheets. When using the species group designations, WS or ES, the specified strengths must be the lowest values for the species in the group.

Footnote 2

Specified strengths are based on covered, dry service conditions of use. Dry service conditions of use are those in which a 19% MC will not be exceeded.

Footnote 3

The Ft values in the table are reduced to reflect the volume effects of length, depth and thickness for a range of common application conditions. The Ft values for the product may be higher when approved by the manufacturer for use as a component of engineered products, which are manufactured under a recognized quality control program. Values shown are for lengths up to 12,497 mm (41 ft).

Return to footnote 3 referrer

Footnote 4

Fb values include allowances for variations in span-to-depth ratio and method of loading, and may be used without further adjustments except as noted below. For product depths other than 305 mm, regardless of thickness, multiply table values by (305/d)^0.136. Adjustments for common depths are shown below. For product depths less than 89 mm, the multiplier for the 89-mm depth must be used.

Depth (mm)	89	140	184	241	305	406	457	610
Multiplier	1.18	1.11	1.07	1.03	1.00	0.96	0.93	0.91

Footnote 5

When structural members qualify as repetitive members in accordance with CSA O86, a 4% increase is permitted for Fb in addition to the increases permitted in Table Note (4). This increase does not apply to field-assembled multi-member beams.

Return to footnote 5 referrer

Footnote 6

For simplicity, use 3.65 MPa for product depths up to 305 mm, and 3.35 MPa for product depths greater than 305 mm. When a more accurate analysis is desired, the allowable horizontal shear for all depths greater than 305 mm is Fv = 3.65 (305/d)^0.065.

Return to footnote 6 referrer

Footnote 7

Fcperp must not be increased for duration of load.

Return to footnote 7 referrer

Footnote 8

Values shown are for thicknesses up to 45 mm. Products stamped with 1047 (products manufactured at the Burlington, Washington plant), are only available in thicknesses up to 45 mm. For thicknesses greater than 45 mm but no more than 89 mm, multiply table values by (45/t)^0.136, where t is the depth of the material in plank orientation.

Return to footnote 8 referrer

Footnote 9

Simple span uniform load deflection is calculated as follows:

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

Where:

Δ = deflection, mm

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

W = specified uniform load, N/m

L = span, m

b = beam width, mm

d = beam depth, mm

Return to footnote 9 referrer

Footnote 10

The Fv (plank/deck orientation) for the products is 2.45 MPa with the following exception: products stamped with 1047 (i.e., manufactured at the Burlington, Washington plant) have an Fv (plank/deck orientation) of 1.80 MPa.

Footnote 11

Some grades may not currently be in production; however, the manufacturer has qualified the grades listed in the table. Contact the manufacturer for more information. These unproduced, prequalified grades may be reintroduced to the market after the manufacturer and third-party certification agency verify that the specified design values conform to the relevant requirements of the CSA O86 edition that is current at the time. The manufacturer and third-party certification agency are responsible for maintaining the values and for informing CCMC of any changes.

Return to footnote 11 referrer

Footnote 12

The design values for 2.0E-2900Fb YP are not based on qualification data, but on the plant's capacity to produce product with higher bending strength (2.0E-3100Fb YP). The manufacturer shall ensure the quality control data can meet the target values set in the manufacturing standard.
