Sentence 9.23.12.3.(3)

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.

For floors and constructions supporting floors, this is to limit the probability of:

• compromised structural integrity, or
• for exterior floors or environmental separators supporting a floor, 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 excessive movement, vibration or deflection, which could lead to negative effects on the psychological well-being of persons.
