Intent 1:
To limit the probability of excessively long spans
of beams or joists, which could lead to beams being unable to resist
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,
- 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:
- for floors and elements that support floors, persons
losing their balance, tripping or falling, or
- the compromised operation of doors or windows required
for egress in an emergency.
This is to limit the probability of harm to persons.
