Intent 1:
To limit the probability of inadequate brick-to-brick
bond strength.
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.
This is to limit the probability of:
- for floors and elements supporting floors, excessive
deflection, which could lead to persons losing their balance, tripping
or falling, or
- where masonry is used in chimneys and fireplaces, the
cracking of masonry units, which could lead to the leakage of combustion
products, which could lead to asphyxiation or acute poisoning.
This is to limit the probability of harm to persons.
