Intent 1:
To limit the probability of an inability to resist
expected gravity loads, which could lead to:
- crushing of floor joists, and sill plates or beams,
- inadequate support for floor joists,
- where not embedded in a foundation, the separation of
joists from supporting members, or
- where not embedded in a foundation, but end-nailed,
strapped or blocked, the twisting of joists.
This is to limit the probability of
the excessive movement, deformation or failure of floor assemblies.
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.
