9.23.11.4.(4)
OS2OP2OH1OH4OS1OS3
ObjectiveOH4 Vibration and Deflection Limitation
Attribution
[F22-OH4] Applies to floors and elements that support floors.
Application
Application 1: 
Minimum dimensions, material, and fastening of ties for top wall plates that are not lapped at corners and intersections and of ties for joints in single plates, in loadbearing wood-frame walls 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 inadequate continuity of joints in single top plates, which could lead to an inability to resist expected lateral loads, which could lead to the excessive deflection or failure of wall plates.
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.
