To limit the probability of:
- an inadequate resistance to concentrated loads imposed
by beams, which could lead to the compressive failure of masonry units,
which could lead to the structural failure of the masonry [see corresponding
requirement in Sentence 184.108.40.206.(2)], or
- an excessively narrow contact area between beams and
hollow masonry, which could lead to wood fibres being crushed, which
could lead to the structural failure of beams.
This is to limit the probability of:
- compromised structural integrity, or
- where elements support or are part of 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 is to limit
the probability of excessive movement, deflection or vibration, which
could lead to negative effects on the psychological well-being of
