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, or
- 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.
For floors and elements supporting floors, this to limit
the probability of excessive deflection or vibration of floors, which
could lead to a loss of balance, tripping or falling, which could
lead to harm to persons.
