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.
Where masonry construction is required
to provide fire resistance, this is to limit the probability of compromised
fire resistance of the assembly, which could lead to harm to persons.
