Product description

The products are prefabricated wood I-joists consisting of six proprietary grade fingerjointed lumber flanges that are graded in accordance with the Pinkwood Quality Assurance Manual and glued flatwise to a 9.5-mm- or 11.1-mm-thick oriented strandboard (OSB) web. The I-joist series are available in depths ranging from 241 mm to 610 mm. Table 1 provides a description of the products.

The OSB web material is installed with the wafer orientation parallel to the length of the joist. The web segments are bonded with a V-joint using a phenol-resorcinol adhesive (see CCMC 13054-L). The flange is bonded to the web using the same adhesive. The flange fingerjoints are bonded with a melamine formaldehyde adhesive (see CCMC 13252‑L).

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 a MC between 6% and 14% according to 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.

Footnote 2

In cases where concrete topping is applied or bridging/blocking is used and joists are installed at the maximum spans, the current vibration criteria may not address all occupant performance expectations. Therefore, Pinkwood Ltd. should be consulted for span adjustments, if necessary, in these types of installations.

Additional test information for the products

The characteristic values obtained from testing to ASTM D5055-13e1, “Standard Specification for Establishing and Monitoring Structural Capacities of Prefabricated Wood I-Joists,” as specified in CSA O86-14, are summarized below. The manufacturer’s published pre-engineered joist spans were designed in accordance with CSA O86-19.

Table 4. Additional test information for the products
Property	Test information
Moment capacity	The moment capacity qualification was carried out using the analytical method based on the characteristics of the flange material, and with confirmatory testing done in accordance with ASTM D5055. Data from confirmatory tests were used to establish the applicable coefficient of variation, CV_w. The reliability normalization factor from Table 16.2.3.2 of CSA O86-14 was used to determine the specified strength.
Shear capacity	The shear capacity was established for each depth separately in accordance with ASTM D5055. Qualification tests have been used to establish the applicable coefficient of variation, CV_w. The reliability normalization factor from Table 16.2.3.2 of CSA O86-14 was used to determine the specified strength.
Stiffness	An appropriate test program was used to confirm the stiffness capacity. The following formula was used to predict mid-span deflection: $Δ_{deflection} = \frac{5 w L^{4}}{384 E I} + \frac{w L^{2}}{K}$ where: w = load (kN/m) L = span (mm) EI and K from Table 2.
End joints	Flange tension tests were conducted in accordance with Section 6.4.1.3. of ASTM D5055. The tensile capacity was determined in accordance with Section 6.4.1.4. of ASTM D5055. Tests have been used to establish the applicable coefficient of variation, CV_w. The reliability normalization factor from Table 16.2.3.2 of CSA O86-14 was used to determine the specified strength.
Creep	Specimens were tested for creep performance in accordance with Section 6.6.3. of ASTM D5055. The specimens recovered more than 90% of the basic dead load deflection.
Bearing length	Qualification tests were conducted to qualify minimum bearing lengths. The I-joist design properties on end reaction and intermediate reaction were analyzed using ASTM D5055. Qualification tests for the reaction values were used to establish the applicable coefficient of variation, CV_w. The reliability normalization factor from Table 16.2.3.2 of CSA O86-14 was used to determine the specified strength.
Adhesive qualification	The web-to-web adhesive and the web-to-flange adhesive comply with CSA O112.7-M1977, "Resorcinol and Phenol-Resorcinol Resin Adhesives for Wood (Room- and Intermediate-Temperature Curing)" (see CCMC 13054-L). The flange fingerjoint adhesive complies with CSA O112.9-04, "Evaluation of Adhesives for Structural Wood Products (Exterior Exposure)" (see CCMC 13252-L).
Web stock	The web stock meets the requirements of CSA O325, "Construction Sheathing," and is certified by APA, a third-party certification agency.

Fire-protection options

The performance of the below fire-protection options are presented as additional information for authorities having jurisdiction. This section is beyond the scope of the CCMC's Code compliance opinion related to the evaluation of structural performance.

Fire performance of innovative structural products

The CCMC Registry of Product Assessments contains opinions on the suitability-for-use of products intended as structural elements in houses. Although historically there has been no need to regulate the structural fire performance of houses, an inherent intent of the National Building Code of Canada (NBC) is that occupants have sufficient time to escape from a building in the event of a fire. There are many factors that may determine whether that intent is achieved. The fire endurance of structural elements may be one. However, its importance may be minimized by other factors such as combustible content load, early warning devices, smoke movement and toxicity, and fire department response time; all contributing to the overall system performance. Research is underway within the NRC Construction Research Centre to determine the critical factors that affect occupant escape from houses.

Some innovative structural products have been used in the marketplace for several years and have gained the confidence of design professionals, code authorities and users with respect to their performance under typical fire scenarios in today's house system. Some newer products have not been in service long enough to have gained that confidence and may present a more obvious concern.

The minimum fire performance of innovative structural materials, or alternative solutions, as compared to that of the NBC-specified conventional wood-frame construction, or acceptable solution, has been the subject of analysis and discussion for several years among fire officials, provincial and territorial regulators, and AHJs. In fire tests conducted between 2002 and 2008 at the NRC, the innovative structural joist systems tested, and currently in the marketplace (i.e., I-joists, C-channel steel joists, metal-plated wood trusses and metal-web trusses), had a time-to-collapse below the performance of exposed 38 mm × 235 mm (2 × 10) lumber joists.

The CCMC provides this floor fire performance information to the local AHJs across Canada to aid their decision-making on whether the fire performance of floors (i.e., the time to evacuate before failure occurs) for alternative joist systems performs “as well as” the inherent fire performance of exposed 38 mm × 235 mm (2 × 10) lumber joists. As is the case for all innovative products, designers and authorities should exercise judgment in considering the use of innovative structural products for houses. Unless otherwise stated, innovative structural products for houses have not been evaluated in the context of the NBC intent noted above.referrer

The CCMC has reviewed the fire-protection options below in comparison to the fire performance of an unprotected, exposed 38 mm × 235 mm (2 × 10) floor joist system. The presented fire-protection options perform “as well as” exposed 38 mm × 235 mm (2 × 10) lumber joists. It should be noted that the NBC 2015 exempts single-family houses constructed using conventional wood-frame construction, in accordance with Part 9, from requiring a fire-resistance rating (see Article 9.10.8.10. of Division B of the NBC 2015). The fire-protection options below for alternative floor joists are not to be considered in sprinklered single-family houses or where fire-resistance-rated assemblies are required.

The following fire-protection assemblies are applicable for the evaluated products as provided in Table 5.

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.
