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 that the use of inappropriate aggregate materials or the presence of an excessive proportion of contaminants in aggregates will lead to the premature failure of concrete under expected environmental or structural loads.

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.
