Attribution
[F22-OH4] Applies to floors and elements that support floors.
Application
Application 1: 
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
Intent 1: 
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.
For floors and constructions supporting floors, this is to limit the probability of:
  • compromised structural integrity, or
  • for exterior floors or environmental separators supporting a floor, 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 excessive movement, vibration or deflection of floors, which could lead to negative effects on the psychological well-being of persons.
Intent 2: 
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.
