Intent 1:
To limit the probability of:
- concentrations of stress from horizontal loads acting
on ties that are vertically aligned, which could lead to cracking,
or
- inadequate embedment of ties in mortar.
This is to limit the probability of:
- buckling or tensile failure of the ties,
- an inadequate resistance to tensile or compressive loads,
- water ingress from rain or melting snow along ties,
which could lead to the corrosion or rotting of structural building
elements, or
- the exposure of ties to water, which could lead to the
corrosion of ties.
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.
