Intent 1:
To limit the probability of:
- flexural failure of the masonry spanning between intermediate
tie locations,
- tie pullout or pushthrough (i.e. embedment failure),
- ties buckling, or
- tie material failure.
This is to limit the probability of cracking or buckling
of cavity wall constructions in areas that typically experience higher
levels of lateral stress.
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,
- in assemblies exposed to moisture or the exterior, damage
and deterioration, or
- an inability to resist expected loads, which could lead
to excessive deflection or vibration of floors.
For floors and elements supporting floors, this is to limit
the probability of persons losing their balance, tripping or falling,
which could lead to harm to persons.
