Intent 1:
To limit the probability of an overly reduced cross-section,
which could lead to an inability to resist expected gravity and lateral
loads, which could lead to excessive movement or deformation, or bending
or buckling failure, which could lead to excessive deflection and
damage to roofing.
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.
