Intent 1:
To limit the probability that the building frame
will be improperly anchored to the foundation, which could lead to:
- an inability to resist expected wind and seismic loads,
which could lead to overturning, lifting or sliding of the superstructure
off the foundation, and
- where the superstructure is required to provide lateral
support for the foundation, an inability to resist expected lateral
earth pressure loads, which could lead to:
- cracking or differential movement of the foundation,
or
- compromised structural integrity of the foundation,
which could lead to deflection or deformation of the superstructure.
Where wood-frame construction supports or is part of an
environmental separator, this is to limit the probability of the displacement
or failure of required environmental separation elements, which could
lead to:
- condensation,
- precipitation ingress,
- excessive heat transfer,
- pollutant ingress, or
- compromised thermal performance of components intended
to resist heat transfer.
This is to limit the probability of:
- inadequate control of temperatures of interior spaces,
drafts, 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.
