Intent

Intent 1:

To limit the probability of an inadequate type, length and number of fasteners, which could lead to an inability to resist expected lateral, gravity or wind uplift loads.

For floors and constructions supporting floors, this is to limit the probability of:

  • compromised structural integrity, or
  • 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.
