Intent 1:

To limit the probability of inadequate strength and stiffness, which could lead to an inability to resist expected dead and live gravity loads transferred from long header joists.

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 of floors, which could lead to negative effects on the psychological well-being of persons.
