9.23.9.4.(2)

Intent 1:

To limit the probability of inadequate restraint of the bottoms of joists, which could lead to excessive twisting of joists, which could lead to an inability to resist expected gravity and lateral loads, which could lead to 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.
