Intent 1:
To limit the probability that the interrupted vertical
reinforcement will not be replaced, or that its replacement will be
excessively remote from the wall opening, which could lead to an inadequate
resistance to expected loads, which could lead to concrete cracking
or the displacement of walls.
Where elements support
or are part of an environmental separator, this is to limit the probability
of:
- condensation,
- rainwater ingress,
- the ingress of moisture, or
- compromised thermal performance of components intended
to provide resistance to heat transfer.
This is to limit the probability of:
- an inadequate control of temperatures of interior spaces,
relative humidity, or water accumulation,
- the generation of pollutants from biological growth
or from materials that become unstable on wetting, or
- deterioration, which could lead to further compromised
integrity of environmental separators.
This is to limit the probability of:
- negative effects on the air quality of indoor spaces,
- the inadequate thermal comfort of persons, and
- contact with moisture.
This is to limit the probability of harm to persons.
