Intent 1:
To limit the probability of:
- inadequate corrosion resistance, which could lead to
the corrosion of metal ties,
- an inadequate cross-sectional area, or
- an inadequate shear area through the mortar.
This is to limit the probability of:
- buckling failure of metal ties under lateral loads,
- tensile failure of metal ties under gravity loads, and
- failure of the bond between mortar and metal ties under
lateral loads.
This is to limit the probability of inadequate load distribution
among the wythes of multiple-wythe masonry walls, which could lead
to an inability to resist transverse or vertical loads, which could
lead to 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.
