Objective:
OS2.1, OS2.3
APPLICATION:
Design lateral pressure on walls, including foundation walls and the walls associated with exterior below-grade entrances and window wells, that are subject to lateral loads
from other than drained earth, in buildings to which Part 9 applies [see Sentence
1.3.3.3.(1) of Division A for application
of Part 9].
INTENT:
To limit the probability that any surcharge on foundation
walls will not be included in the design pressures, which could lead to the
walls being unable to resist 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, or
- 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.
This is to limit the probability of harm to persons.

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.

APPLICATION:
Design lateral pressure on walls, including foundation walls and walls associated with exterior below-grade entrances and window wells, that are subject to lateral loads from other than

walls being unable to resist lateral pressure, which could lead to the cracking

For walls
serving as an environmental separator or supporting an environmental separator,
this is to limit the probability of:
- pollutant ingress (from the exterior or from adjacent interior space, including soil gas, combustion products from parking garages, or particulates),
- precipitation ingress,
- condensation, or
- moisture ingress from the ground.
This is to limit the probability of:
- an inadequate control of 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 compromised integrity of elements supported by foundation walls.
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.
