  3. OH1
  4. OS3
  5. OS1
  6. OH4

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 blocking or furring providing inadequate support and nailing surfaces for vertical edges of interior finishes, sheathing or cladding materials, which could lead to inadequate strength of wood-frame assemblies, which could lead to an inability to resist expected vertical or lateral loads.

This is to limit the probability of:

  • detachment or separation of interior finishes, sheathing or cladding from supporting members,
  • displacement of sheathing or cladding, or
  • inadequate racking resistance for exterior walls and lateral support of walls, where finishes, sheathing or cladding provide required racking or buckling resistance.

This is to limit the probability of compromised structural integrity, which could lead to:

  • the structural collapse of wood-frame construction, or
  • where wood-frame construction supports or is part of an environmental separator, the excessive deformation, displacement or failure of required environmental separation elements, which could lead to deterioration, which could lead to further compromised structural integrity.

This is to limit the probability of harm to persons.
