Intent 1:
To limit the probability of:
- inadequate leverage provided by the inboard portion
of cantilevered joists,
- inadequate resistance, by headers and fasteners, to
upward reactions, or
- inadequate fastening of the inboard portion of cantilevered
joists.
This is to limit the probability of:
- the excessive movement, deformation or failure of floor
assemblies, or
- the excessive deflection of the roof.
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.
