Objective

OH4 Vibration and Deflection Limitation

Attribution

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

Intent

Intent 1:

To limit the probability that the upper storey braced wall panel will be excessively stronger than the lower storey braced wall band, which could lead to a weak storey, which could lead to compromised structural integrity, which could lead to excessive racking.

For floors and constructions supporting floors, this is to limit the probability of:

  • compromised structural integrity, or
  • for exterior walls 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.
