Intent 1:
To limit the probability of inadequate restraint
of the bottoms of floor joists, which could lead to the excessive
twisting of joists, which could lead to an inability to resist expected
gravity and lateral loads, which could lead to the excessive movement,
deformation or failure of floor assemblies.
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.
