Objective

OH4 Vibration and Deflection Limitation

Attribution

[F20-OH4]Applies to floors and elements that support floors.

Intent

Intent 1:

To limit the probability of:

  • flexural failure of the masonry spanning between intermediate tie locations,
  • tie pullout or pushthrough (i.e. embedment failure),
  • ties buckling, or
  • tie material failure.

This is to limit the probability of cracking or buckling of cavity wall constructions in areas that typically experience higher levels of lateral stress.

This is to limit the probability of:

  • compromised structural integrity of masonry construction,
  • where masonry construction is part of an environmental separator, the displacement or failure of required environmental separation elements, which could lead to deterioration.

For floors and elements supporting floors, this is to limit the probability of excessive movement, deflection or vibration, which could lead to negative effects on the psychological well-being of persons.
