Sentence 9.23.14.10.(1)

Intent 1:

To limit the probability of inadequate depth, which could lead to inadequate strength, which could lead to an inability to resist bending stress imposed by struts or dwarf walls in addition to other expected gravity and lateral loads, which could lead to:

• the failure of the roof or of the ceiling joists, or
• the excessive deflection of the roof, which could lead to opening of joints.

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.
