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
This is to limit the probability of cracking or buckling.
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.
