Intent 1:
To limit the probability of excessively long spans,
which could lead to an inability to resist expected lateral, gravity
or wind-uplift loads.
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.
