This research was done to evaluate the feasibility of using for manufacturing glulam beams. The physical and mechanical properties of the glulam beam were evaluated, and these properties were compared to those of the solid solid timber. The glulam beam's physical and mechanical properties were all superior to solid timber. In comparison to solid timber, glulam's density, water absorption (WA), linear expansion (LE), and thickness swelling (TS) all improved by 11.1, 48.4, 44.6, and 37.0%, respectively. Again, compared to solid timber, the modulus of rupture (MOR) and modulus of elasticity (MOE) of the glulam beam increased by 27.6 and 29.2%, respectively. Additionally, the ASTM specifications were met by the glulam beam. As a result, based on the properties, it is possible to make glulam beams as structural timber products.
本研究旨在评估使用[具体材料]制造胶合木梁的可行性。对该胶合木梁的物理和力学性能进行了评估，并将这些性能与实木[具体木材种类]进行了比较。该胶合木梁的物理和力学性能均优于实木[具体木材种类]。与实木[具体木材种类]相比，胶合木的密度、吸水率（WA）、线性膨胀率（LE）和厚度膨胀率（TS）分别提高了11.1%、48.4%、44.6%和37.0%。此外，与实木[具体木材种类]相比，该胶合木梁的抗弯强度（MOR）和弹性模量（MOE）分别提高了27.6%和29.2%。另外，该胶合木梁符合美国材料与试验协会（ASTM）的规范。因此，基于这些性能，可以将胶合木梁制成结构木材产品。
需注意，原文中部分[具体材料]和[具体木材种类]表述未明确给出，翻译时用[具体材料]和[具体木材种类]暂代，你可根据实际情况替换准确内容。
