Objective

OH4 Vibration and Deflection Limitation

Attribution

[F22-OH4]Applies to floors and elements that support floors.

Intent

Intent 1:

To limit the probability of discontinuity of top plates, which could lead to an inability to resist expected gravity and lateral loads, which could lead to:

  • the inadequate transfer of vertical loads to and from studs, which could lead to the excessive deflection or failure of wall plates, or
  • inadequate diaphragm action of plates, which could lead to the excessive deflection of 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.
