Objective

OP2 Structural Sufficiency of the Building

Attribution

[F20,F22-OP2.3]Applies to elements that support or are part of an environmental separator.

Intent

Intent 1:

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 in beams.

This is to limit the probability of compromised structural integrity, which could lead to:

  • structural failure,
  • 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, or
  • an inability to resist expected loads, which could lead to
    • the excessive deformation or deflection of walls, and
    • 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.
