Intent 1:
To limit the probability that the placement or amount
and spacing of horizontal reinforcement will not be adequate:
- to ensure the reinforcement is encased and bonded to
the concrete, or
- to limit cracking due to temperature changes and shrinkage.
This is to limit the probability of:
- compromised structural integrity, or
- where elements support or are part of an environmental
separator, the displacement or failure of required environmental separation
elements, which could lead to the deterioration of building elements.
For floors and elements supporting floors, this is to limit
the probability of excessive movement, deflection or vibration, which
could lead to negative effects on the psychological well-being of
persons.
