9.20.9.4.(9)

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:

  • flexural failure of the masonry spanning between intermediate tie locations,
  • tie pullout or pushthrough (i.e. embedment failure),
  • ties buckling, or
  • tie material failure.

This is to limit the probability of cracking or buckling of cavity wall constructions in areas that typically experience higher levels of lateral stress.

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.
