9.23.5.5.(1)

Intent 1:

To limit the probability of an overly reduced cross-section, which could lead to an inability to resist expected gravity and lateral loads, which could lead to excessive movement or deformation, or bending or buckling failure, which could lead to excessive deflection and damage to roofing.

This is to limit the probability of compromised structural integrity, which could lead to:

• the structural collapse of wood-frame construction, or
• where wood-frame construction supports or is part of an environmental separator, 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.
