To limit the probability that masonry exterior walls
will be unable to resist expected structural loads.
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.
