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.
Where walls support floors, this is
to limit the probability of:
- the excessive deformation of floors, which could lead
to compromised operation of doors required for egress in an emergency,
and
- excessive deflection or vibration of floors, which could
lead to persons losing their balance, tripping or falling.
This is to limit the probability of harm to persons.
