Objective:

OS2.1, OS2.5, OS2.3

 

APPLICATION:

Fastening of lumber exterior-wall framing to lumber floor framing, in wood-frame constructions to which Section 9.23. applies [see Sentence 9.23.1.1.(1) for application of Section 9.23.], where the sole plate is not fastened to the floor joists or blocking with nails at least 82 mm long spaced not more than 400 mm o.c.

INTENT:

To limit the probability of inadequate fastening or an excessive rate of deterioration of fasteners, which could lead to an inability to resist expected wind loads, which could lead to the separation of exterior walls or wall elements from floors, which could lead to overturning, lifting or sliding of exterior walls.
This is to limit the probability of compromised structural integrity, which could lead to:
  • fastened elements detaching from supporting members, which could lead to elements falling from the building,
  • 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.
To exempt situations from the application of Sentence 9.23.3.4.(1) where another means of fastening the wall framing to the floor framing is provided.
