Intent 1:
To limit the probability of the excessive deflection
of structural members.
This is to limit the probability
of:
- compromised integrity of non-structural and structural
components of the building, including ceiling membranes,
- for roof framing, rainwater ingress into or through
assemblies, which could lead to deterioration, which could lead to
compromised structural integrity of roofs or of building elements
protected by roofs,
- for roof framing, ceiling joists or floor framing supporting
air barrier materials, vapour barriers or insulation, condensation
on interior surfaces or within assemblies or condensation of moisture
from interior spaces, which could lead to deterioration, which could
lead to compromised structural integrity of the roof, ceiling or floor
or assemblies supported or protected by these assemblies, and
- excessive springiness or deflection of floor and roof
systems,
This is to limit the probability of:
- the space being unsuitable for its intended use, or
- damage to the building.
