Functional Statement:
F20
To support and withstand expected loads and
forces.
F22
To limit movement under expected loads and
forces.
Objective:
OH1.1, OH1.2, OH1.3
INTENT:
To limit the probability of inadequate fastening or an excessive
rate of deterioration of fasteners, which could lead to an inability to resist
expected wind loads, which could lead to the separation of exterior walls
or wall elements from floors, which could lead to overturning, lifting or
sliding of exterior walls.
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.
To exempt situations from the application of
Sentence
9.23.3.4.(1) where
another means of fastening the wall framing to the floor framing is provided.
