ObjectiveOH4 Vibration and Deflection Limitation
Attribution
[F22-OH4] Applies to floors and elements that support floors.
Application
Application 1: 
Design of corners of intersecting 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 studs providing inadequate support and nailing surfaces for vertical edges of interior finishes, sheathing or cladding materials, which could lead to inadequate strength of wood-frame assemblies, which could lead to an inability to resist expected vertical or lateral loads.
This is to limit the probability of:
  • detachment or separation of interior finishes, sheathing or cladding from supporting members,
  • displacement of sheathing or cladding, or
  • inadequate racking resistance for exterior walls and lateral support of walls, where finishes, sheathing or cladding provide required racking or buckling resistance.
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.
