Intent 1:
To limit the probability of inadequate joist strength
or inadequate composite strength and stiffness 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, which could lead to:
- 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.
