9.23.11.1.(2)


Objective	OP2 Structural Sufficiency of the Building
Attribution	[F20-OP2.1,OP2.5] [F22-OP2.4,OP2.5] [F20,F22-OP2.3] Applies to elements that support or are part of an environmental separator.
Application	Application 1: Minimum thickness of bottom wall plates, in wood-frame constructions to which Section 9.23. applies [see Sentence 9.23.1.1.(1) for application of Section 9.23.]: where wall studs are located directly over framing members, or in non-loadbearing walls.

Intent	Intent 1: To limit the probability of inadequate thickness of bottom wall plates in walls where stud loads are limited or are transferred directly to other supporting members, which could lead to an inability to resist expected gravity and lateral loads, which could lead to: the inadequate distribution of vertical loads to and from studs, which could lead to the excessive deflection or failure of wall plates, inadequate diaphragm action of plates, which could lead to the excessive deflection of walls, or inadequate lateral support for the ends of studs. 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: the space being unsuitable for its intended use, compromised operation of windows or doors, or damage to the building.
