Objective

OP2 Structural Sufficiency of the Building

Attribution

Intent

Intent 1:

To limit the probability of the inadequate connection of rafters at ridges, which could lead to:

  • an inability to transfer expected gravity loads or positive wind loads at their upper ends, or
  • an inability to resist expected negative wind loads, which could lead to tension separation of roof peaks.

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.
