ATTRIBUTION:

Functional Statement:

F20

To support and withstand expected loads and forces.

F22

To limit movement under expected loads and forces.

Objective:

OS2.1, OS2.3, OS2.5, OS2.3, OS2.5

 

APPLICATION:

Staggered end joints for diagonally-applied lumber wall sheathing used to provide bracing, in wood-frame constructions to which Section 9.23. applies [see Sentence 9.23.1.1.(1) for application of Section 9.23.].

INTENT:

To limit the probability of discontinuity in the sheathing, which could lead to an inability to resist expected lateral or gravity loads, which could lead to the excessive movement, deformation or failure of exterior walls.
This is to limit the probability of compromised structural integrity, which could lead to:
  • structural collapse, or
  • the excessive deformation, displacement or failure of required environmental separation elements, which could lead to deterioration, which could lead to further compromised structural integrity of environmental separators.
This is to limit the probability of harm to persons.

APPLICATION:

Staggered end joints for diagonally-applied lumber wall sheathing used to provide bracing, in wood-frame constructions to which Section 9.23. applies [see Sentence 9.23.1.1.(1) for application of Section 9.23.].

INTENT:

To limit the probability of discontinuity in the sheathing, which could lead to an inability to resist expected lateral or gravity loads, which could lead to the excessive movement, deformation or failure of exterior walls.
This is to limit the probability of the displacement or failure of required environmental separation elements, which could lead to:
  • condensation,
  • precipitation ingress,
  • excessive heat transfer,
  • pollutant ingress, or
  • compromised thermal performance of components intended to resist heat transfer.
This is to limit the probability of:
  • an inadequate control of temperatures of interior spaces, drafts, relative humidity or water accumulation,
  • the generation of pollutants from biological growth or from materials that become unstable on wetting, or
  • deterioration, which could lead to further compromised integrity of environmental separators.
This is to limit the probability of:
  • negative effects on the air quality of indoor spaces,
  • the inadequate thermal comfort of persons, and
  • contact with moisture.
This is to limit the probability of harm to persons.
