Functional Statement:

F20

To support and withstand expected loads and forces.

F22

To limit movement under expected loads and forces.

F20

To support and withstand expected loads and forces.

F22

To limit movement under expected loads and forces.

Objective:

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

APPLICATION:

Design of corners of intersecting walls, 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 studs providing inadequate support and nailing surfaces for vertical edges of interior finishes, sheathing or cladding materials, which could lead to inadequate strength of wood-frame assemblies, which could lead to an inability to resist expected vertical or lateral loads.

This is to limit the probability of:

detachment or separation of interior finishes, sheathing or cladding from supporting members,
displacement of sheathing or cladding, or
inadequate racking resistance for exterior walls and lateral support of walls, where finishes, sheathing or cladding provide required racking or buckling resistance.

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

the structural collapse of wood-frame construction, or
where wood-frame construction supports or is part of an environmental separator, 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 harm to persons.

Objective:

OH1.1, OH1.2, OH1.3

APPLICATION:

Design of corners of intersecting walls, in wood-frame constructions to which Section 9.23. applies [see Sentence 9.23.1.1.(1) for application of Section 9.23.].

INTENT:

This is to limit the probability of:

detachment or separation of interior finishes, sheathing or cladding from supporting members,
displacement of sheathing or cladding, or
inadequate racking resistance for exterior walls and lateral support of walls, where finishes, sheathing or cladding provide required racking or buckling resistance.

Where wood-frame construction supports or is part of an environmental separator, 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:

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.
