To limit the probability of:
- inadequate bearing support across all laminates, which
could lead to shear failure at the interface of laminates in built-up
wood beams, which could lead to structural failure of beams, or
- insufficient contact area between the top of the columns
and the beams they support, which could lead to crushing of wood fibres
This is to limit the probability of compromised structural
integrity, which could lead to:
- structural failure, or
- for environmental separators or elements supporting
an environmental separator, excessive deformation or deflection of
exterior walls or roofs, which could lead to 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.
