Intent 1:
To limit the probability of inadequate end bearing
area, which could lead to excessive localized stress, which could
lead to:
- crushing of concrete at the base of the footing (or
of wood at the top, where a column supports a wood beam), or
- shear failure of wood beams (parallel to the grain),
which could lead to the structural failure of beams.
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.
