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, or
- an inability to resist expected loads, which could lead
to:
- the excessive movement or deformation of walls, or
- the excessive deflection or vibration of floors.
This is to limit the probability of:
- the space being unsuitable for its intended use,
- compromised operation of windows or doors, or
- damage to the building.
