Intent 1:
To limit the probability of:
- inadequate load distribution among floor joists,
- inadequate backing for insulation, or
- inadequate support for air barrier systems.
This is to limit the probability of
an inability to resist expected gravity loads.
For floors and constructions supporting floors, this is
to limit the probability of:
- compromised structural integrity, or
- for exterior floors or environmental separators supporting
a floor, 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 excessive movement,
vibration or deflection of floors, which could lead to negative effects
on the psychological well-being of persons.
