Intent 1:
To limit the probability of:
- inadequate width of masonry units in loadbearing contact
with each other, which could lead to an inability to resist expected
gravity or lateral loads,
- insufficient bond strength to resist tensile stresses
in non-loadbearing masonry cavity walls, or
- inadequate bonding of ties with mortar, which could
lead to inadequate pullout and pushout resistance.
This is to limit the probability of compromised structural
integrity, which could lead to:
- structural failure of masonry construction,
- 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, or
- in assemblies exposed to moisture or the exterior, damage
and deterioration, which could lead to further compromised structural
integrity.
This is to limit the probability of harm to persons.
