ObjectiveOS2 Structural Safety
Attribution
[F20,F22-OS2.3] Applies to elements that support or are part of an environmental separator.
Application
Application 1: 
Tying of double top plates at corners and intersections of loadbearing stud walls, 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 an inadequate connection between wall assemblies that provide transverse support, which could lead to an inability to resist expected lateral loads, which could lead to the excessive deflection or failure of walls.
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.
Intent 2: 
To provide a cross-reference to Sentence 9.23.11.4.(4) and thereby further define its application.
