9.23.14.1.(1)

Objective

OS2 Structural Safety

Attribution

[F20,F22-OS2.3]Applies to elements that support or are part of an environmental separator.

Intent

Intent 1:

To limit the probability of joints in structural members or unsupported splice joints, which could lead to inadequate strength or stiffness to resist expected gravity or wind loads, which could lead to the excessive deflection or failure of roofs.

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.
