Effect of Low Temperatures on the Block Shear Strength of Norway Spruce Glulam Joints

BioResources, 2016
The block shear strength of Norway spruce (Picea abies (L.) Karst.) glulam joints was tested under low temperatures. Glulam samples were glued with the three of the most common outdoor structural adhesives. The cold temperatures tested were 20, −20, −30,
