Intent 1:
For columns exposed to the weather, to limit the
probability that the columns will rust at an excessive rate, which
could lead to the premature failure of the columns.
This is to limit the probability of compromised structural
integrity, which could lead to:
- structural failure,
- for environmental separators or elements supporting
an environmental separator, the displacement or failure of required
environmental separation elements, which could lead to the deterioration
of building elements, or
- an inability to resist expected loads, which could lead
to
- the excessive deformation or deflection of walls, and
- the excessive deflection or vibration of floors.
This is to limit the probability of:
- the space being unsuitable for its intended use, or
- damage to the building.
