Objective

OP2 Structural Sufficiency of the Building

Attribution

[F20,F22,F80-OP2.3]Applies to elements that support or are part of an environmental separator.

Intent

Intent 1:

To limit the probability of:

  • excessive corrosion of straps,
  • inadequate strength of straps, or
  • failure of the bond between mortar and straps under lateral loads.

This is to limit the probability of buckling or tensile failure of the straps under lateral loads, which could lead to the excessive flexing of masonry veneer, which could lead to cracking or buckling.

This is to limit the probability of:

  • compromised structural integrity of the masonry, or
  • where masonry veneer serves as cladding, the excessive movement or deformation of the cladding, which could lead to excessive precipitation ingress, which could lead to deterioration, which could lead to further compromised structural integrity of environmental separators or elements supported or protected by such separators.

This is to limit the probability of damage to the building.
