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 of:

  • concentrations of stress in areas that typically experience higher levels of lateral stress (e.g. around openings), which could lead to an inability to resist transverse or vertical loads, and
  • inadequate load distribution among the wythes of multiple-wythe masonry walls.

This is to limit the probability of cracking or buckling.

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, 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, or
  • damage to the building.
