Intent

Intent 1:

To limit the probability of an inability to resist expected gravity loads, which could lead to:

  • crushing of floor joists, and sill plates or beams,
  • inadequate support for floor joists,
  • where not embedded in a foundation, the separation of joists from supporting members, or
  • where not embedded in a foundation, but end-nailed, strapped or blocked, the twisting of joists.

This is to limit the probability of the excessive movement, deformation or failure of floor assemblies.

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.

This is to limit the probability of excessive deflection or vibration of floors, which could lead to persons losing their balance, tripping or falling, which could lead to harm to persons.
