Intent

Intent 1:

To limit the probability of:

  • inadequate load distribution among floor joists,
  • inadequate backing for insulation, or
  • inadequate support for air barrier systems.

This is to limit the probability of an inability to resist expected gravity loads.

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.
