9.20.9.4.(6)

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:

  • concentrations of stress in areas that typically experience higher levels of lateral stress (e.g. around openings), which could lead to an inability to resist transverse or vertical loads, and
  • inadequate load distribution among the wythes of multiple-wythe masonry walls.

This is to limit the probability of cracking or buckling.

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.
