Intent 1:
To limit the probability of:
- inadequate leverage provided by the inboard portion
of cantilevered joists,
- inadequate resistance, by headers and fasteners, to
upward reactions, or
- inadequate fastening of the inboard portion of cantilevered
joists.
This is to limit the probability of:
- the excessive movement, deformation or failure of floor
assemblies, or
- the excessive deflection of the roof.
This is to limit the probability of compromised structural
integrity, which could lead to:
- the structural collapse of wood-frame construction,
or
- for exterior floors or floors supporting environmental
separators, 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:
- the space being unsuitable for its intended use,
- compromised operation of windows or doors, or
- damage to the building.
