9.20.7.5.(1)

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 that face shells, which provide most of the loadbearing capacity of hollow units, will be removed, which could lead to an inability to accommodate vertical and horizontal loads, which could lead to cracking.

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

  • structural failure of masonry construction, or
  • 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.

This is to limit the probability of harm to persons.
