Objective

OS2 Structural Safety

Attribution

[F20,F80-OS2.3]Applies to elements that support or are part of an environmental separator.

Intent

Intent 1:

To limit the probability that the performance of cement and aggregate under expected structural and environmental loads will fall significantly below expectations, which could lead to cracking at mortar joints and inadequate bonding to masonry units.

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.
