Pacific Woodtech LVL

Product description

Pacific Woodtech LVL (see Figure 1) is manufactured by laminating Douglas Fir veneer sheets coated with a phenolic adhesive in specific lay-up patterns in a continuous press with all grain oriented parallel to the length of the member. The ends of the veneer sheets are either butt- or scarf-cut according to the requirements of the lay-up pattern, then lapped. The lay-up patterns and adhesives used are as specified in Pacific Woodtech Corporation’s “Quality Control Manual for Laminated Veneer Lumber.”

The product is available in thicknesses ranging from 19 mm to 178 mm, depths from 44 mm to 1 219 mm, and lengths up to 20.3 m. Products with a thickness greater than 89 mm are fabricated by means of a secondary face-bonding process.

The phenol-formaldehyde (PF) adhesive used in the manufacture of this laminated veneer lumber (LVL) complies with CSA O112.6-M1977, “Phenol and Phenol-Resorcinol Resin Adhesives for Wood (High-Temperature Curing).” A phenol resorcinol formaldehyde (PRF) adhesive (Momentive 4001/5830 hardener), used in the secondary face-bonding process at a certified laminating plant, conforms to CSA O112.9-10, “Adhesives for Structural Wood Products (Exterior Exposure).” LT75/FM260 PRF adhesive, used in the secondary face-bonding process when face-bonded at another certified laminating plant, conforms to CSA O112.7-1960, “Resorcinol and Phenol-Resorcinol Resin Adhesives for Wood (Room- and Intermediate-Temperature Curing).”

Notes:

Footnote 1

All lumber, wood-based panels and proprietary engineered wood products are intended for “dry service conditions.” “Dry service” is defined as the in-service environment under which the average equilibrium moisture content (MC) of lumber is 15% or less over a year and does not exceed 19% at any time. Wood contained within the interior of dry, heated or unheated buildings has generally been found to have an MC of between 6% and 14%, depending on season and location. During construction, all wood-based products should be protected from the weather to ensure that the 19% MC is not exceeded, in accordance with Article 9.3.2.5., Moisture Content, of Division B of the NBC 2015.

Additional information

The design values obtained from testing to ASTM D 5456-14b as specified in CSA O86-14 (Update No. 1), “Engineering Design in Wood,” are summarized below. The manufacturer’s published pre-engineered beam and header spans were then designed in accordance with CSA O86-14 (Update No. 1).

Table 3. Additional test information for Pacific Woodtech LVL
Property	Test information
Bending	Specimens were tested in edgewise and flatwise bending for qualification and for establishing volume effects. A non-parametric, 5% tolerance limit with 75% confidence level approach was used to determine the characteristic value. Qualification test data have been used to establish the applicable coefficient of variation, CV_w, and the reliability normalization factor from CSA O86-14 was used to determine the specified strength. True (shear free) modulus of elasticity (MOE) was determined by testing a total of two hundred and forty 2.0E specimens of different sizes and analyzing data following the procedures of Sections 45 through 52 of Appendix X4 of ASTM D198-15, "Standard Test Methods of Static Tests of Lumber in Structural Sizes". The results also justified 1.5E true MOE values. Values more conservative than those justified were chosen for simplicity.
Shear	Specimens were tested edgewise and flatwise orientation. A non-parametric, 5% tolerance limit with 75% confidence level approach was used to determine the characteristic value. Qualification test data have been used to establish the applicable coefficient of variation, CV_w, and the reliability normalization factor from CSA O86-14 was used to determine the specified strength.
Compression perpendicular to grain (edgewise)	Specimens were tested edgewise and the average stress at a 1.0-mm deformation was determined. This value was multiplied by 1.09 to establish the specified strength.
Compression perpendicular to grain (flatwise)	Specimens were tested flatwise and the lower of the average stress at 1.0-mm deformation or the average stress at the proportional limit was determined in accordance with ASTM D 5456-14b. This value was multiplied by 1.81 to establish the specified strength in accordance with CSA O86-14 (Update No. 1).
Compression parallel to grain	Specimens were tested and a non-parametric, 5% tolerance limit with 75% confidence level approach was used to determine the characteristic value. Qualification test data have been used to establish the applicable coefficient of variation, CV_w, and the reliability normalization factor from CSA O86-14 was used to determine the specified strength.
Tension parallel to grain	Specimens were tested in tension for qualification and to establish volume effects. A non-parametric, 5% tolerance limit with 75% confidence level approach was used to determine the characteristic value. Qualification test data have been used to establish the applicable coefficient of variation, CV_w, and the reliability normalization factor from CSA O86-14 was used to determine the specified strength.
Nail withdrawal	Nail withdrawal values were established following ASTM D1761-06, “Standard Test Methods for Mechanical Fasteners in Wood,” for an 8d common nail having a 31.75-mm penetration. Twenty specimens were tested and the equivalent specific gravity along with the equivalent species combination was determined in accordance with ASTM D 5456-01, A2.
Nail bearing	Dowel bearing strength was determined as per ASTM D 5764-95, “Standard Test Method for Evaluating Dowel-Bearing Strength of Wood and Wood-Based Products,” with 10d common nails with a nominal diameter of 3.76 mm and a lead hole diameter of 2.77 mm. Forty specimens (10 specimens for four combinations of load direction) of each LVL were tested and the mean bearing capacity was used to establish the equivalent specific gravity and equivalent species combination as per ASTM D 5456-01, A2.
Bolt bearing	Bolt bearing capacity as per ASTM D 5764-95 with 12.5-mm and 19.0-mm bolts was determined. Twenty specimens (10 specimens for two combinations) of each LVL were tested and the mean bolt bearing capacity was used to establish the equivalent specific gravity and equivalent species combination as per ASTM D 5456-01, A2.
Creep and recovery	Thirty specimens of Pacific Woodtech LVL were tested within a three-month creep and recovery test program, resulting in acceptable performance demonstrating equivalency to duration of load behavior of lumber.
Adhesive	The phenol-formaldehyde adhesive used in the manufacture of this LVL complies with CSA O112.6-M1977, “Phenol and Phenol-Resorcinol Resin Adhesives for Wood (High-Temperature Curing).” See CCMC 13019-L. A phenol resorcinol formaldehyde adhesive (Momentive 4001 / 5830 hardener), used in the secondary face-bonding process when face-bonded at a certified laminating plant, conforms to CSA O112.9-10, “Adhesives for Structural Wood Products (Exterior Exposure).” See CCMC 13522-L. LT75/FM260 phenolic resorcinol formaldehyde adhesive, used in the secondary face-bonding process when face-bonded at another certified laminating plant, conforms to CSA O112.7-1960, “Resorcinol and Phenol-Resorcinol Resin Adhesives for Wood (Room- and Intermediate-Temperature Curing).”
Bond quality	The bond quality was evaluated in accordance with Section 6.7.2 of ASTM D 5456-10a based on longitudinal shear (block shear) tests per Section 14 of ASTM D 143. The test results confirmed the longitudinal (flatwise) shear design value of 2 350F_b-1.9E and evaluated the percentage of wood failure. The average percentage of wood failure tested was deemed to be acceptable (no less than 85%).
Product durability	The product durability was evaluated in accordance with Section 6.8.1 of ASTM D 5456-10a based on the single vacuum-pressure-soak cycle edgewise bending tests. The test results indicated that the 3 100F_b-2.0E LVL met the ASTM D 5456 edgewise bending durability requirement, which requires the average strength retention to be at least 75%.

Code Compliance via Alternative Solutions

Where a design differs from the acceptable solutions in Division B, then it should be treated as an "alternative solution." A proponent of an alternative solution must demonstrate that the alternative solution addresses the same issues as the applicable acceptable solutions in Division B and their attributed objectives and functional statements. However, because the objectives and functional statements are entirely qualitative, demonstrating compliance with them in isolation is not possible. Therefore, Clause 1.2.1.1.(1)(b) identifies the principle that Division B establishes the quantitative performance targets that alternative solutions must meet. In many cases, these targets are not defined very precisely by the acceptable solutions [...] Nevertheless, Clause 1.2.1.1.(1)(b) makes it clear that an effort must be made to demonstrate that an alternative solution will perform as well as a design that would satisfy the applicable acceptable solutions in Division B—not “well enough” but “as well as.”

National Building Code of Canada, Sentence A-1.2.1.1.(1)(b)

The CCMC has determined that compliance with this provision of the Code has been demonstrated as an Alternative Solution. The evaluation report provides a summary of the basis of CCMC's compliance opinion.

CCMC's code compliance opinions

All CCMC evaluation reports are opinions of code compliance established in accordance with the National Building Code of Canada, Subsection 1.2.1. "Compliance with this Code," which requires compliance to be achieved by:

complying with the applicable acceptable solutions in Division B, or
using an alternative solution that will achieve at least the minimum level of performance required by Division B in the areas defined by the objective and functional statements attributed to the applicable acceptable solutions.

The CCMC assesses compliance with Canadian building, energy and safety codes, and is trusted by over 6,000 regulators across Canada.
