Intent

Intent 1:

To limit the probability that struts will be unable to transfer compressive roof loads to loadbearing walls, which could lead to inadequate intermediate support for rafters or roof joists.

This is to limit the probability of compromised structural integrity, which could lead to:

  • the structural collapse of wood-frame construction,
  • where roof and ceiling framing members support required elements of environmental separators, the excessive deformation, displacement or failure of these elements, which could lead to deterioration, which could lead to further compromised structural integrity of roofs or environmental separators, or
  • where roof and ceiling framing members support assemblies exposed to the exterior, excessive water ingress, which could lead to deterioration.

This is to limit the probability of harm to persons.
