Intent 1:

To limit the probability of:

• inadequate load distribution among floor joists,
• inadequate backing for insulation, or
• inadequate support for air barrier systems.

This is to limit the probability of an inability to resist expected gravity loads.

Where assemblies are required to provide fire resistance, this is to limit the probability of excessive deflection of the roof, which could lead to compromised fire resistance of the assembly, which could lead to harm to persons.
