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.
