[F20-OS2.1,OS2.5]
[F22-OS2.5]
[F20,F22-OS2.3] Applies to elements that support or are part of an environmental separator.
Application
Application 1: 
Minimum length of end bearing of lumber floor joists, in wood-frame constructions to which Section 9.23. applies [see Sentence 9.23.1.1.(1) for application of Section 9.23.].
Exceptions: 
except as stated in Sentence 9.23.9.1.(2), which applies to joists bearing on ribbon boards.

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, which could lead to:
  • the structural collapse of wood-frame construction, or
  • for exterior floors or floors supporting environmental separators, 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.
