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, 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.
