Objective

OP2 Structural Sufficiency of the Building

Attribution

[F20-OP2.3][F40,F61-OP2.3,OP2.4]Applies to elements that support or are part of an environmental separator.

Intent

Intent 1:

To limit the probability of:

  • an inadequate distribution of roof or floor loads transmitted through framing elements, which could lead to overstressing of hollow masonry units,
  • an inadequate barrier, which could lead to termites accessing structural wood elements, or
  • the ingress of water into the cores of hollow masonry units.

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.
