9.23.10.3.(3)


Objective	OS2 Structural Safety
Attribution	[F20-OS2.1,OS2.5] [F22-OS2.5] [F20,F22-OS2.3] Applies to elements that support or are part of an environmental separator.
Application	Application 1: Orientation of wall studs, in wood-frame constructions to which Section 9.23. applies [see Sentence 9.23.1.1.(1) for application of Section 9.23.], that support only a load from an attic not accessible by a stairway, where: the portion of the roof supported by the studs does not exceed 2.1 m in width, the minimum stud size, maximum stud spacing, and maximum unsupported stud height do not exceed the limits stated in Table 9.23.10.1., and the studs are clad on not less than one side with plywood, OSB or waferboard fastened with structural adhesive.

Intent	Intent 1: To limit the probability that studs installed 'on the flat' will not act compositely with the sheathing and will be subject to excessive gravity and lateral loads, which could lead to an inability to resist expected gravity and lateral loads. This is to limit the probability of compromised structural integrity, which could lead to: the structural collapse of wood-frame construction, or where wood-frame construction supports or is part of an environmental separator, the excessive deformation, displacement or failure of required environmental separation elements, which could lead to deterioration, which could lead to further compromised structural integrity. This is to limit the probability of harm to persons.
