9.23.9.1.(2)

Intent 1:

To limit the probability of inadequate support for joists, which could lead to an inability to resist expected gravity loads.

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

• compromised structural integrity, or
• where members support or are part of an environmental separator, the displacement or failure of required environmental separation elements, which could lead to deterioration.

This is to limit the probability of excessive deflection or vibration of floors, which could lead to persons losing their balance, tripping or falling, which could lead to harm to persons.
