  2. OS2
  3. OP2
  4. OS1
  5. OS3
  6. OH4

Objective

OP2 Structural Sufficiency of the Building

Attribution

[F20,F61,F55-OP2.3][F61,F55-OP2.4]Applies to elements that support or are part of an environmental separator.

Intent

Intent 1:

To limit the probability of:

  • interruption of the hydration process,
  • freezing and expansion of internal water, and
  • over-watering due to the melting of ice.

This is to limit the probability of the failure of internal bonds in the concrete, which could lead to reduced compressive strength, which could lead to an inadequate resistance to:

  • expected environmental or structural loads, or
  • air and moisture transfer.

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

  • structural failure,
  • where concrete supports or is used in an environmental separator, the displacement or failure of required environmental separation elements, which could lead to the deterioration of building elements, which could lead to further compromised structural integrity, or
  • an inability to resist expected loads, which could lead to
    • excessive deformation or deflection of walls, and
    • excessive deflection or vibration of floors.

This is to limit the probability of:

  • the space being unsuitable for its intended use,
  • compromised operation of windows and doors, and
  • damage to the building.
