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.
Where assemblies are required to provide fire resistance,
this is to limit the probability of compromised fire resistance of
the assembly, which could lead to harm to persons.
