9.20.2.1.(1)

Objective

OS2 Structural Safety

Attribution

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

Intent

Intent 1:

To limit the probability that performance, with respect to loadbearing capacity, water transfer and freeze-thaw resistance, will fall significantly below expectations, which could lead to an inability to resist expected gravity or lateral loads, as well as moisture or temperature loads.

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

  • 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.
