| Application | Application 1: Minimum sizes and maximum spans of ridge beams that
are 38 mm by 140 mm or larger, and that are supported
every 1.2 m or less, in wood-frame constructions to which Section 9.23. applies [see Sentence 9.23.1.1.(1) for application
of Section 9.23.]. |

| Intent | Intent 1: To supersede the requirements for ridge beam support stated
in Sentence (2), in constructions where spans of
ridge beams are limited and appropriate support conditions are provided.
This is to limit the probability of the excessive deflection or
deformation of supporting members, which could lead to compromised operation
of doors or windows required for egress in an emergency, which could lead
to harm to persons.
