Objective

OP2 Structural Sufficiency of the Building

Attribution

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

Intent

Intent 1:

To limit the probability of an inability to resist expected gravity loads, which could lead to:

  • crushing of floor joists, and sill plates or beams,
  • inadequate support for floor joists,
  • where not embedded in a foundation, the separation of joists from supporting members, or
  • where not embedded in a foundation, but end-nailed, strapped or blocked, the twisting of joists.

This is to limit the probability of the excessive movement, deformation or failure of floor assemblies.

This is to limit the probability of compromised structural integrity, which could lead to:

  • the structural collapse of wood-frame construction, or
  • for exterior floors or floors supporting environmental separators, the excessive deformation, displacement or failure of required environmental separation elements, which could lead to deterioration, which could lead to further compromised structural integrity.

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.
