Objective

OP2 Structural Sufficiency of the Building

Attribution

[F20,F80-OP2.3]Applies to elements that support or are part of an environmental separator or are exposed to moisture.

Intent

Intent 1:

To limit the probability that performance, with respect to loadbearing capacity, water transfer and freeze-thaw resistance, will fall significantly below expectations, which could lead to an inability to resist expected gravity or lateral loads, as well as moisture or temperature loads.

This is to limit the probability of:

  • compromised structural integrity of masonry construction,
  • where masonry construction is part of an environmental separator, the displacement or failure of required environmental separation elements, which could lead to deterioration,
  • in assemblies exposed to moisture or the exterior, damage and deterioration, or
  • an inability to resist expected loads, which could lead to:
    • the excessive movement or deformation 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,
  • compromised operation of windows or doors, and
  • damage to the building.
