  5. OH4
  6. OS3

Objective

OP2 Structural Sufficiency of the Building

Attribution

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

Intent

Intent 1:

To limit the probability that the performance of the ties will fall significantly below expectations, with respect to:

  • corrosion resistance,
  • resistance to buckling, tensile failure and withdrawal under compression and tensile loads, and
  • transferring lateral loads from one wythe to another.

This is to limit the probability of inadequate load distribution among the wythes of multiple-wythe masonry walls, which could lead to an inability to resist transverse or vertical loads, which could lead to 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.
