Intent 1:
To limit the probability of excessively long spans,
which could lead to inadequate strength to support the additional
weight of a concrete topping, which could lead to excessive deflection
or failure.
This is to limit the probability
of:
- compromised structural integrity,
- for environmental separator or elements supporting 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.
