Intent 1:
To limit the probability of inadequate thickness
of bottom wall plates in walls where stud loads are limited or are
transferred directly to other supporting members, which could lead
to an inability to resist expected gravity and lateral loads, which
could lead to:
- the inadequate distribution of vertical loads to and
from studs, which could lead to the excessive deflection or failure
of wall plates,
- inadequate diaphragm action of plates, which could lead
to the excessive deflection of walls, or
- inadequate lateral support for the ends of studs.
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.
