Notes:

Footnote 1

Grade designations (i.e., 2.1E 3100/2150) identify the values for MOE as shear-free E (E_true), Allowable Stress Design (ASD) flexural strength (F_b), and the product with the highest ASD tensile strength (F_t). Grade designations for products with the lowest tensile strength may also be labeled to be F_b and F_t values (i.e., 2.1E 2800 is equivalent to 2.1E 2800/1950).

Return to footnote 1 referrer

Footnote 2

Grade designations (i.e., 2.0 2800/1950) identify the values for MOE as apparent E (E_apparent), ASD flexural strength (F_b), and the product with the lowest ASD tensile strength (F_t). Grade designation for the products with the highest tensile strength may also be labeled to both F_b and F_t values (i.e., 2.0 3100 is equivalent to 2.0 3100/2150).

Footnote 3

The Thorsby, AL plant (Mill No. 1086) only produces 1.8E 2650/1650, 1.9E 2750/1825, 2.0E 2850/1950 and 2.1E 3100/2150 grades (or equivalent apparent E grade designations).

Footnote 4

The specified tensile strength is for a 6 096-mm-long LVL member. For other lengths, multiply by length factor, K_L = (6096/L)^1/8, where L is the member length in mm. An increase in tension strength for lengths less than 1 219 mm is not permitted. In addition, the maximum cross section is limited to three times the tested specimen's cross sectional area. Contact the manufacturer for the maximum cross section for tension applications.

Footnote 5

The specified flexural strength is for a 305-mm-deep LVL member. For other depths, multiply by size factor, K_zb = (305/d)^1/9, where d is the member depth in mm.

Return to footnote 5 referrer

Footnote 6

The reference MOE for beam stability and column stability calculations, E_min, must be calculated using E_apparent in accordance with Clause 15.3.3.5, "Slenderness Factor, K_c," of CSA O86.

Return to footnote 6 referrer

Footnote 7

For uniformly loaded, simple span beams, deflection is calculated as follows:

$Δ_{true} = \frac{156 w L^{4} \times 10^{6}}{E_{true} b d^{3}} + \frac{2400 w L^{2}}{E_{true} b d}$ $Δ_{apparent} = \frac{156 w L^{4} \times 10^{6}}{E_{apparent} b d^{3}}$

Δ = deflection, mm

w = uniform load, N/m

L = span, m

E = modulus of elasticity, MPa

b = beam width, mm

d = beam depth, mm
