| dc.description.abstract | Trembling aspen (Populus tremuloides) is abundant in Canada but is widely considered an underutilized species. This study was aimed at evaluating the potential of using aspen lumber to produce cross-laminated timber (CLT), glued-laminated timber (glulam), and wood I-joists. The key mechanical properties of these engineered wood products, which were fabricated using a modified grading criterion, were examined. It was found that 1) The mean effective bending stiffness and characteristic bending moment resistance of 5-layer CLT specimens in the major-strength direction were 5,069×10⁹ N·mm²/m and 97.65×106 N·mm/m; 2) The mean apparent MOE and characteristic modulus of rupture of glulam specimens were 12,315 MPa and 27.00 MPa; and 3) The mean effective stiffness and characteristic bending moment resistance of wood I-joist specimens were 899×106 kN·mm2 and 9,730 kN·mm. It could be concluded that properly sorted aspen lumber could be used in the production of CLT, glulam, and wood I-joists for specific applications. | |
