The shear capacity of the specimens was established by combining data in accordance with ASTM D 5055. Data from quality control (QC) tests was used to establish the applicable coefficient of variation, CV_w, and the reliability normalization factor from Table 14.2.3.2 of CAN/CSA-O86 was used to determine the specified strength.

The moment capacity qualification was carried out using the analytical method based on the characteristics of the flange material, with confirmatory testing in accordance with ASTM D 5055. Data from QC tests was used to establish the applicable coefficient of variation, CV_w, and the reliability normalization factor from Table 14.2.3.2 of CAN/CSA-O86 was used to determine the specified strength.

An appropriate test program was used to confirm the stiffness capacity. The following formula was used to predict mid-span deflection:

$\text{deflection}=\frac{5w{L}^4}{384EI}+\frac{w{L}^2}{K}$

where deflection (in mm), w = unfactored uniform load (kN/mm), L = design span (mm), EI (kN·mm2) and K (kN) were taken from Table 4.1.1.

End joints were qualified as part of the flange tension qualification. The flanges are finger-joined at the plant, and regular tension testing is conducted.

Specimens were tested for creep performance in accordance with ASTM D 5055. The specimens recovered more than 90% of the basic dead load deflection.

Tests were conducted to qualify, with and without web stiffeners, minimum end-bearing lengths of 38 mm, 44 mm, 89 mm and 102 mm, as well as interior bearing lengths of 89 mm and 140 mm. Qualification tests were used to establish the applicable coefficient of variation, CVw, and the reliability normalization factor from Table 14.2.3.2 of CAN/CSA-O86 was used to determine the specified strength.

For the products manufactured at the Pohénégamook plant, all joints are bonded together using a polyurethane adhesive, UX-160/WD3-A322 (CCMC 13513-L).
