Objective

OH4 Vibration and Deflection Limitation

Attribution

[F80-OH4]Applies to floors and elements that support floors.

Intent

Intent 1:

To limit the probability that such concrete blocks will be of inadequate mass or absorb excessive amounts of water, which could lead to inadequate resistance to freeze-thaw stresses.

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, or
  • in assemblies exposed to moisture or the exterior, damage and 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.
