To limit the probability of inadequate end support for floor joists, which could lead to an inability to resist expected gravity loads, which could lead to the excessive movement, deformation or failure of floor assemblies.

This is to limit the probability of:

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