Intent 1:
To limit the probability of discontinuity of top
plates, which could lead to an inability to resist expected gravity
and lateral loads, which could lead to:
- the inadequate transfer of vertical loads to and from
studs, which could lead to the excessive deflection or failure of
wall plates, or
- inadequate diaphragm action of plates, which could lead
to the excessive deflection of walls.
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.
