Objective | OS2 Structural Safety |
Attribution | |
Application | Application 1: Lateral support for collar ties that are longer than 2.4
m and that act as intermediate support for lumber roof joists and rafters
sloped at 1 in 3 or more, 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 limit the probability of inadequate lateral support for
collar ties, which could lead to an inability to resist expected compressive
loads transferred from rafters, which could lead to buckling of collar ties,
which could lead to rafter failure, which could lead to structural collapse,
which could lead to harm to persons. |
