Objective

OP2 Structural Sufficiency of the Building

Attribution

Intent

Intent 1:

To supersede the requirements for ridge beam support stated in Sentence (2), in constructions where spans of ridge beams are limited and appropriate support conditions are provided.

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.
