Intent 1:
To limit the probability that OSB cladding will
not be strong enough or rigid enough.
Where panel-type
cladding is installed as bracing to satisfy Subclause 9.23.13.1.(2)(a)(i) and Clause 9.23.13.6.(1)(a), this is to limit the probability
of an inadequate resistance to lateral loads, which could lead to
racking of exterior walls.
This is to limit the probability of:
- the deformation of the building,
- the excessive deformation, displacement or failure of
required environmental separation elements, which could lead to deterioration,
which could lead to compromised structural integrity of exterior walls
or of elements supported or protected by exterior walls, or
- falling cladding components.
This is to limit the probability of:
- the space being unsuitable for its intended use,
- compromised operation of windows and doors, or
- damage to the building.
