| Attribution | |
| Application | Application 1: Collar ties or ceiling joists providing intermediate
support for roof rafters or joists, in wood-frame constructions to which Section 9.23. applies [see Sentence 9.23.1.1.(1) for application
of Section 9.23.], where the roof slope is 1 in 3 or greater.

| Intent | Intent 1: To limit the probability of inadequate strength of intermediate
support for rafters, which could lead to an inability to resist expected compressive
loads transferred from opposing rafters, which could lead to failure of intermediate
support members. 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 further define the application of the span tables.
