Abstract This paper presents an experimental investigation to identify suitable indices to assess durability of glulam when
subjected to freeze-thaw cycles in an exposed enviroenment. In this study, two types of glulam specimens were
tested for their performance when subjected to different levels of aging due to freezing and thawing. Effect of
aging treatment on various parameters including thickness swelling rate, static bending strength, elastic modulus,
shear strength, and peeling rate of adhesive layer were studied. Obtained results showed that freeze-thaw aging
treatment did not affect the water-resistance of the specimens as measured by thickness swelling rate and had
little effect… More >
