OH4 Vibration and Deflection Limitation


[F20,F22-OH4]Applies to floors and elements that support floors.


Intent 1:

To limit the probability of:

  • inadequate bearing support across all laminates, which could lead to shear failure at the interface of laminates in built-up wood beams, which could lead to structural failure of beams, or
  • insufficient contact area between the top of the columns and the beams they support, which could lead to crushing of wood fibres in beams.

This is to limit the probability of:

  • compromised structural integrity, or
  • for environmental separators or elements supporting an environmental separator, the displacement or failure of required environmental separation elements, which could lead to the deterioration of building elements.

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