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 of the ends of studs.
For floors and constructions supporting
floors, this is to limit the probability of:
- compromised structural integrity, or
- for exterior floors or environmental separators supporting
a floor, 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 excessive movement,
vibration or deflection, which could lead to negative effects on the
psychological well-being of persons.
