  1. OS2
  2. OP2
  3. OH1
  4. OH4
  5. OS3

Objective

OP2 Structural Sufficiency of the Building

Attribution

[F20-OP2.3]Applies to elements that support or are part of an environmental separator.

Intent

Intent 1:

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¬†9.20.8.4.(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, or
  • an inability to resist expected loads, which could lead to
    • 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.
