|---|---|
| Shear capacity |
The shear capacity of the specimens was established by combining data in accordance with ASTM D 5055-04. Data from quality control (QC) tests were used to establish the applicable coefficient of variation, CVw, and the reliability normalization factor from Table 13.2.3.2 of CAN/CSA-O86-01 was used to determine the specified strength. |
| Moment capacity |
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 5055-04. Data from QC tests were used to establish the applicable coefficient of variation, CVw, and the reliability normalization factor from Table 13.2.3.2 of CAN/CSA-O86-01 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:
where w = load (kN/mm), L = span (mm), EI and K are taken from Tables 4.1.1.1 and 4.1.1.2 |
| End joints |
End joints were qualified as part of the flange tension qualification. The flanges are in-plant finger-joined, and regular tension testing is conducted. |
| Creep |
Specimens were tested for creep performance in accordance with ASTM D 5055-04. The specimens recovered more than 90% of the basic dead load deflection. |
| Bearing length |
End and intermediate reactions were tested and calculated in accordance with ASTM D 5055-12 and CAN/CSA- O86-09 where the applicable coefficient of variation, CVw, and the reliability normalization factor from Table 13.2.3.2 of CAN/CSA-O86-01 was used to determine the specified strength. |
| Adhesive qualification |
The web/web joint, flange/web joint and flange finger joints are bonded with a polyurethane adhesive (see CCMC 13512-L, CCMC 13513-L and CCMC 13591-L). |
| Web stock |
The web stock complies with CAN/CSA-O325.0-92, "Construction Sheathing." |
