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.
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,
or
- the 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.
