Intent 1:
To limit the probability of insufficiently deep
or excessively long lintels, which could lead to the inadequate transfer
of expected gravity loads from roof, wall or floor framing to supporting
studs.
This is to limit the probability of:
- compromised structural integrity,
- where elements support or are part of an environmental
separator, the failure of required environmental separation elements,
which could lead to deterioration, or
- an inability to resist expected loads, which could lead
to:
- the excessive deflection or vibration of floors, or
- the excessive movement or deformation of walls.
This is to limit the probability of:
- compromised operation of doors or windows required for
egress in an emergency, and
- persons losing their balance, tripping or falling.
This is to limit the probability of harm to persons.
