9.23.16.5.(2)

Intent 1:

To limit the probability that the roof system will not be capable of providing the necessary load-resisting diaphragm action, which could lead to uneven distribution of the lateral loads to the supporting walls, which could lead to an inability to resist expected lateral loads, which could lead to excessive racking.

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

• the structural collapse of wood-frame construction, or
• 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:

• the space being unsuitable for its intended use,
• compromised operation of doors or windows, and
• damage to the building.
