9.23.9.6.(1)

Intent 1:

To limit the probability of inadequate strength and stiffness, which could lead to an inability to resist expected dead and live gravity loads transferred from long header joists.

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.
