Product information

Product name

BCI®Joists

Product description

The product is a prefabricated wood I-joist available in 12 series. Five of the twelve series are manufactured with western species wood, while the remaining seven are manufactured with southern species wood. The I-joist is made from laminated veneer lumber (LVL) flanges with an oriented strandboard (OSB) web. The flanges are made from laminating veneers of Douglas Fir, Southern Yellow Pine, Western Hemlock and eucalyptus (see CCMC 12472-R.) The top and bottom flanges are available in depths ranging from 29 mm to 38 mm and widths ranging from 51 mm to 89 mm. The web consists of 9.5-mm or 11.1-mm thick OSB in 1 219-mm segments. The flange width, depth and grade are listed in Table 1 below.

The web-flange connection is made by inserting the profiled OSB web into a profiled groove in the centre of the wide face of the flange (both top and bottom flanges). The web-to-web joints are bonded with a polyurethane emulsion polymer (PEP) adhesive and the web-to-flange joints are bonded with an emulsion polymer isocyanate (EPI) adhesive.

The products listed in Table 1 below are the products that have been tested and are currently being manufactured by Boise Cascade Company. See Offered products with calculated properties below for a list of the products, with their calculated properties, that can be manufactured.

Additional test information for the products

The design values obtained from testing to ASTM D5055-08a, “Standard Specification for Establishing and Monitoring Structural Capacities of Prefabricated Wood I-Joists,” and in compliance with ASTM D5055-13e1 , as specified in CSA O86-14, are summarized below. The manufacturer’s published pre-engineered joist spans were then designed in accordance with CSA O86-14.

Table 3. Additional test information for the products
Property Test information
Shear capacity The shear capacity of the BCI® Joists series was established by testing in accordance with ASTM D5055. Qualification and quality-control tests were used to establish the applicable coefficient of variation, CVw, and the reliability normalization factor from Table 16.2.3.2 of CSA O86 was used to determine the specified strength.
Moment capacity The moment capacity qualification was carried out using the analytical method in accordance with ASTM D5055. Qualification and quality control tests were used to establish the applicable coefficient of variation, CVw, and the reliability normalization factor from Table 16.2.3.2 of CSA O86 was used to determine the specified strength.
Stiffness

A bending test program of varying depths was used to confirm the stiffness capacity. The following formula should be used to predict mid-span deflection:

deflection = (5wL4)/(384EI × 103) + (wL2)/K

where: w = uniform load (kN/m), L = span (mm), and EI and K are taken from the Technical information section.

Creep The specimens were tested for creep performance as per ASTM D5055, which states that two specimens from each I-joist series group shall be loaded to 1.5 times the design resistive moment capacity for 1 hour and unloaded to basic dead load. The average deflection recovery must exceed 90% of the deflection between the basic dead load (20% design) and the end of the 1-hour load period of 1.5 times the total load.
Bearing length Tests were conducted to qualify a minimum bearing length of 38 mm and 44 mm at end supports, and 89 mm at intermediate supports. Qualification tests were used to establish the applicable coefficient of variation, CVw. The reliability normalization factor from Table 16.2.3.2 of CSA O86 was used to determine the specified end reaction capacity and intermediate reaction capacity at the minimum bearing length.
Adhesive qualification The web-to-web joints are bonded with a polyurethane emulsion polymer (PEP) adhesive (see CCMC 13511-L and CCMC 13512-L) and the web-to-flange joints are bonded with an emulsion polymer isocyanate (EPI) adhesive (see CCMC 13591-L).

 

Fire-protection options

The performance of the fire-protection options below 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 performs “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 below fire-protection options 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 4.
