9.23.3.4.(2)

Intent 1:

To limit the probability of inadequate fastening or an excessive rate of deterioration of fasteners, which could lead to an inability to resist expected wind loads and seismic effects, which could lead to the separation of exterior walls or wall elements from floors, which could lead to overturning, lifting or sliding of exterior walls.

This is to limit the probability of:

• compromised structural integrity,
• where elements support or are part of an environmental separator, the failure of required environmental separation elements, which could lead to deterioration, or
• an inability to resist expected loads, which could lead to:
  • the excessive deflection or vibration of floors, or
  • the excessive movement or deformation of walls.

This is to limit the probability of:

• compromised operation of doors or windows required for egress in an emergency, which could lead to delays in the evacuation or movement of persons to a safe place, and
• persons losing their balance, tripping or falling.

This is to limit the probability of harm to persons.

Intent 2:

To exempt situations from the application of Sentence 9.23.3.4.(1) where another means of fastening the wall framing to the floor framing is provided.
