| Application | Application 1: Minimum depth of lumber ceiling joists supporting
struts or dwarf walls that in turn support roof rafters, where the roof slope

| Intent | Intent 1: To limit the probability of 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:
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.
Intent 2: To limit the application of Sentence (1) for
constructions where support for increased roof loads has to be provided.
