Intent 1:
To limit the probability of:
- excessive corrosion of straps,
- inadequate strength of straps, or
- failure of the bond between mortar and straps under
lateral loads.
This is to limit the probability of
buckling or tensile failure of the straps under lateral loads, which
could lead to the excessive flexing of masonry veneer, which could
lead to cracking or buckling.
This is to limit the probability of:
- compromised structural integrity of the masonry, or
- where masonry veneer serves as cladding, the excessive
movement or deformation of the cladding, which could lead to excessive
precipitation ingress, which could lead to deterioration, which could
lead to further compromised structural integrity of environmental
separators or elements supported or protected by such separators.
This is to limit the probability of damage to the building.
