Intent
Intent 1: 
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.
Where assemblies are required to provide fire resistance, this is to limit the probability of compromised fire resistance of the assembly, which could lead to harm to persons.
