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 inadequate thickness of bottom wall plates in walls where stud loads are limited or are transferred directly to other supporting members, which could lead to an inability to resist expected gravity and lateral loads, which could lead to:

  • the inadequate distribution of vertical loads to and from studs, which could lead to the excessive deflection or failure of wall plates,
  • inadequate diaphragm action of plates, which could lead to the excessive deflection of walls, or
  • inadequate lateral support of the ends of studs.

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, which could lead to negative effects on the psychological well-being of persons.
