OH4 Vibration and Deflection Limitation


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


Intent 1:

To limit the probability that the eccentric loading of footings will lead to uneven pressure on soil beneath columns, which could lead to soil settlement and footing and column failure.

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.

Intent 2:
