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,
- where elements support or are part of an environmental
separator, the failure of required environmental separation elements,
which could lead to deterioration, or
- an inability to resist expected loads, which could lead
to:
- the excessive deflection or vibration of floors, or
- the excessive movement or deformation of walls.
This is to limit the probability of:
- compromised operation of doors or windows required for
egress in an emergency, and
- persons losing their balance, tripping or falling.
This is to limit the probability of harm to persons.
