[F20,F22-OS3.1]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 accommodate vertical and horizontal loads, which could lead to cracking or structural failure.

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, or
  • an inability to resist expected loads, which could lead to excessive deflection or vibration of floors.

For floors and elements supporting floors, this is to limit the probability of persons losing their balance, tripping or falling, which could lead to harm to persons.
