Intent 1:
To limit the probability of an inadequate thickness
or inappropriate specifications or rating of wall sheathing, 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.
For floors and elements supporting floors, this is to limit
the probability of:
- compromised structural integrity, or
- the displacement or failure of required environmental
separation elements, which could lead to deterioration.
This is to limit the probability of excessive deflection
or vibration, which could lead to persons losing their balance, tripping
or falling, which could lead to harm to persons.
