Intent 1:
To limit the probability of inadequate restraint
of the bottoms of floor joists, which could lead to the excessive
twisting of joists, which could lead to an inability to resist expected
gravity and lateral loads, which could lead to the excessive movement,
deformation or failure of floor assemblies.
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.
