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 of masonry construction,
- where masonry construction is part of an environmental
separator, the displacement or failure of required environmental separation
elements, which could lead to deterioration, or
- in assemblies exposed to moisture or the exterior, damage
and deterioration.
For floors and elements supporting floors, this is to limit
the probability of excessive movement, deflection or vibration, which
could lead to negative effects on the psychological well-being of
persons.
