Intent 1:
To limit the probability of:
- insufficient compressive strength to resist expected
gravity and lateral loads, or
- the excessive shrinkage, cracking and premature failure
of concrete.
This is to limit the probability of:
- compromised structural integrity, or
- where concrete supports or is used in an environmental
separator, the displacement or failure of required environmental separation
elements, which could lead to the deterioration of building elements,
which could lead to compromised structural integrity.
This is to limit the probability of:
- excessive deflection or vibration of supported wood-frame
floors or steps, which could lead to persons losing their balance,
tripping or falling, and
- the failure of fireplaces or chimneys, which could lead
to the leakage of combustion products, including carbon monoxide gas,
into living space, which could lead to the asphyxiation or acute poisoning
of persons.
This is to limit the probability of harm to persons.
