| Attribution | |
| Application | Application 1: Minimum depth of lumber ceiling joists supporting
struts or dwarf walls that in turn support roof rafters, in wood-frame constructions
to which Section 9.23. applies [see Sentence 9.23.1.1.(1) for

| Intent | 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:
This is to limit the probability of compromised
structural integrity, which could lead to:
This is to limit the probability of harm to persons.
