Intent 1:
To limit the probability of inadequate capacity
to transfer loads from supported floor and roof framing members in
construction where a lintel will serve the function of a second top
plate, 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,
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.
