Intent 1:
To limit the probability of an inadequate diameter
of screws, which could lead to inadequate capacity or rigidity, which
could lead to an inability to resist expected dead and live gravity
loads, which could lead to fastened elements detaching from supporting
members, which could lead to excessive movement, deformation or deflection.
This is to limit the probability of compromised structural
integrity, which could lead to:
- fastened elements detaching from supporting members,
which could lead to elements falling from the building,
- 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.
