Intent 1:
To limit the probability of inadequate bearing and
fastening dimensions between walls and their supports, and eccentricity
between load and support, 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 of wall plates
and walls, or
- inadequate diaphragm action of plates, which could lead
to the excessive deflection of walls.
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.
