OH4 Vibration and Deflection Limitation


(a)[F20,F21,F80-OH4]Applies to elements that support floors.


Intent 1:

To limit the probability of:

  • insufficient compressive strength to resist expected gravity and lateral loads, or
  • the excessive shrinkage, cracking and premature failure of concrete.

This is to limit the probability of the excessive deformation of concrete, which could lead to:

  • compromised structural integrity, or
  • where concrete elements support an environmental separator, the displacement or failure of required environmental separation elements, which could lead to the deterioration of building elements, which could lead to compromised structural integrity.

Where concrete elements support wood-frame floors, this is to limit the probability of deflection or vibration of such floors, which could lead to negative effects on the psychological well-being of persons.
