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 D5055-13e1. Data from confirmatory tests were used to establish the applicable coefficient of variation, CVw. 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 as per ASTM D5055-13e1. Qualification tests have been used to establish the applicable coefficient of variation, CVw. 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:
where: w = load (kN/m), L = span (mm), EI and K from Table 4.1. |
End joints |
Flange tension tests were conducted in accordance with Section 6.4.1.3. of ASTM D5055-13e1. The tensile capacity was determined in accordance with Section 6.4.1.4. of ASTM D5055-13e1. Tests have been used to establish the applicable coefficient of variation, CVw. 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 D5055-13e1. 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 D5055-13e1. Qualification tests for the reaction values were used to establish the applicable coefficient of variation, CVw. 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. |
