Attribution

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

Intent

Intent 1:

To limit the probability that masonry adjacent to chases or recesses will be unable to resist concentrated vertical loads or to transfer horizontal loads to supporting elements, which could lead to cracking.

This is to limit the probability of:

  • compromised structural integrity of masonry construction,
  • where masonry construction is part of an environmental separator, the displacement or failure of required environmental separation elements, which could lead to deterioration.

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.
