Intent 1:
To limit the probability of an inability to resist
gravity, lateral or impact loads.
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.
Intent 2:
To limit the probability of an inability to withstand
high temperatures, which could lead to the cracking of masonry units,
which could lead to the leakage of combustion products, which could
lead to asphyxiation or acute poisoning, which could lead to harm
to persons.
