Intent
Intent 1: 
To limit the probability of inadequate joist support, which could lead to an inability to resist expected gravity loads, which could lead to the excessive movement, deformation or failure of floor assemblies.
Where assemblies are required to provide fire resistance, this is to limit the probability of compromised fire resistance of the assembly, which could lead to harm to persons.
