Intent 1:
To limit the probability of inadequate restraint
of the bottoms of joists, which could lead to 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.
