| 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 have been 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 quality control (QC) tests have been 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/m), L = span (mm), EI and K from Table 4.1.1.1 and 4.1.1.2, and d = joist depth (mm). |
| End joints |
End joints were qualified as part of the flange tension qualification. The flanges are in-plant fingerjointed, 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 |
The product reaction properties listed in Tables 4.1.2 and 4.1.4 are specific to bearing lengths shown and are based on a rational bearing analysis methodology applicable to "TJI ® Series Joists." Data submitted confirm satisfactory performance to the rational methodology. Reaction properties for end or intermediate bearing lengths within ranges shown in Tables 4.1.2 and 4.1.4 may be determined by linear interpolation. Extrapolation of reaction properties in Tables 4.1.2 and 4.1.4 is not allowed. |
| Adhesive qualification |
For the "TJI ® s31, s33, and s47 Series Joists," the adhesive for the flange fingerjoints is a polyurethane adhesive (see CCMC 13512-L). The other adhesives used comply with CSA O112.7-M1977, "Resorcinol and Phenol-Resorcinol Resin Adhesives for Wood (Room- and Intermediate- Temperature Curing)" (see CCMC 13054-L). For the remaining products in this series the adhesive used complies with CSA O112.7-M1977, "Resorcinol and Phenol-Resorcinol Resin Adhesives for Wood (Room- and Intermediate- Temperature Curing)" (see CCMC 13054-L). |
