[F20-OS3.1]Applies to floors and elements that support floors.

Intent

Intent 1:

To limit the probability of discontinuity in mortar joints at vertically aligned webs of hollow masonry units, which could lead to:

  • mortar joints of inadequate tensile and compressive strength, or
  • the inadequate containment of grout.

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,
  • in assemblies exposed to moisture or the exterior, damage and deterioration, or
  • an inability to resist expected loads, which could lead to the 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.
