9.20.4.3.(3)

Objective

OS2 Structural Safety

Attribution

[F20-OS2.3]Applies to elements that support or are part of an environmental separator.

Intent

Intent 1:

To limit the probability of discontinuity in the mortar joints of solid masonry units, which could lead to mortar joints of inadequate tensile and compressive strength.

This is to limit the probability of compromised structural integrity, which could lead to:

  • the structural failure of masonry construction,
  • where masonry construction is part of an environmental separator, the excessive deformation, displacement or failure of required environmental separation elements, which could lead to deterioration, which could lead to further compromised structural integrity, or
  • in assemblies exposed to moisture or the exterior, damage and deterioration, which could lead to further compromised structural integrity.

This is to limit the probability of harm to persons.
