OH4 Vibration and Deflection Limitation

Attribution

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

Intent

Intent 1:

To limit the probability that the use of inappropriate or substandard mortar will lead to cracking at mortar joints and inadequate bonding to masonry units, which could lead to the inadequate performance or premature failure of concrete block foundation walls under expected environmental or structural loads.

This is to limit the probability of:

  • compromised structural integrity, or
  • where elements support or are part of 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 is to limit the probability of excessive movement, deflection or vibration, which could lead to negative effects on the psychological well-being of persons.
