Intent 1:
To limit the probability that using inappropriate
design pressures will lead to the walls being unable to resist expected
lateral pressure, which could lead to the cracking of foundations
or building superstructures.
This is to limit
the probability of compromised structural integrity, which could lead
to:
- structural failure,
- for environmental separators or elements supporting
environmental separators, the displacement or failure of required
environmental separation elements, which could lead to the deterioration
of building elements, which could lead to further compromised structural
integrity, or
- an inability to resist expected loads, which could lead
to
- the excessive deformation or deflection of walls, or
- 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.
Intent 2:
To expand the application of Section 4.2. to walls supporting drained earth that are not
constructed in accordance with Section 9.15.
