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.
