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 126.96.36.199.(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, which could lead to:
- structural failure,
- 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,
- an inability to resist expected loads, which could lead
- 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.
