GB/T 40048-2021

This standard specifies test methods for determining the mechanical properties of bolted connections in structural wood and wood-based materials, including load-bearing capacity, stiffness, and failure modes. It is applied in the construction industry for evaluating timber structures, such as wooden frames, trusses, and bridges, during design verification or quality control testing. The standard ensures consistent and reliable performance assessment of bolted joints used in engineered wood products like glulam and cross-laminated timber.
