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 of masonry construction,
- where masonry construction is part of an environmental
separator, the displacement or failure of required environmental separation
elements, which could lead to deterioration.
For floors and elements supporting floors, this is to limit
the probability of excessive movement, deflection or vibration, which
could lead to negative effects on the psychological well-being of
persons.
