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, which could lead to:
- the structural collapse of wood-frame construction,
or
- where wood-frame construction supports or is part of
an environmental separator, the excessive deformation, displacement
or failure of required environmental separation elements, which could
lead to deterioration, which could lead to further compromised structural
integrity.
This is to limit the probability of:
- the space being unsuitable for its intended use,
- compromised operation of windows or doors, or
- damage to the building.
