Intent 1:
To limit the probability of inadequate restraint
of the lower edges of joists, which could lead to excessive twisting
of joists, which could lead to an inability to resist expected gravity
and lateral loads.
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.
