Application
Application 1: 
Fabrication of glued-laminated wood structural components of buildings.
This applies to buildings described in Sentence 1.3.3.2.(1) of Division A and buildings to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A] that are required to be designed to the requirements of Part 4.

Intent
Intent 1: 
To limit the probability that the fabrication of glued-laminated wood structural components results in structural properties during the expected life of the building, which are less than those assumed for design in accordance with CAN/CSA-O177-M, which could lead to:
  • excessive deformation of, or excessive stress in, structural components, which could lead to damage to the building, and
  • excessive deflection or excessive vibration of structural members, which could impede the intended use and occupancy of the building.
