Intent 1:
To limit the probability of an inability to resist
expected lateral loads, which could lead to differential movement
of sheathing board ends, which could lead to damage to cladding and
the sheathing membrane, which could lead to:
- an inadequate fastening base for cladding,
- inadequate support for required cladding and elements
of an environmental separator, or
- an inability to resist expected lateral or gravity loads,
where sheathing provides the required resistance to racking and buckling.
This is to limit the probability of:
- falling cladding,
- the deformation or displacement of cladding, or
- the excessive deflection of the wall.
This is to limit the probability of compromised structural
integrity, which could lead to:
- structural collapse, or
- the deformation, displacement or failure of required
environmental separation elements, which could lead to deterioration,
which could lead to further compromised structural integrity of the
wall or constructions supported by the wall.
This is to limit the probability of:
- the space being unsuitable for its intended use,
- compromised operation of windows or doors, or
- damage to the building.
