Sentence 9.23.13.4.(3)

Intent 1:

To limit the probability of inadequate lateral support at a discontinuity in the floor diaphragm, which could lead to an inability to resist expected lateral loads, which could lead to excessive racking.

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

• compromised structural integrity, or
• for exterior walls 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 of floors, which could lead to negative effects on the psychological well-being of persons.
