Intent 1:
To limit the probability of:
- concentrations of stress in areas that typically experience
higher levels of lateral stress (e.g. around openings), which could
lead to an inability to resist transverse or vertical loads, and
- inadequate load distribution among the wythes of multiple-wythe
masonry walls.
This is to limit the probability of cracking or buckling.
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.
