9.23.14.3.(1)

Objective

OP2 Structural Sufficiency of the Building

Attribution

[F20,F22-OP2.3]Applies to elements that support or are part of an environmental separator.

Intent

Intent 1:

To limit the probability of:

  • inadequate support for roof joists and rafters, which could lead to an inability to resist expected gravity loads, which could lead to crushing, or
  • insufficient area for fastening, which could lead to an inability to resist expected lateral or wind-uplift loads, which could lead to the separation of roofs from walls.

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 damage to the building.
