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.
This is to limit the probability of
compromised structural integrity, which could lead to:
- the structural collapse of wood-frame construction,
or
- where wood-frame construction supports or is part of
an environmental separator, 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 harm to persons.
