Sentence 9.23.14.9.(1)

Intent 1:

To limit the probability that low-strength interior finishes will be relied on to provide lateral restraint, which could lead to an inability to resist expected gravity or lateral loads or shrinkage stresses due to drying, which could lead to joists twisting, which could lead to failure of the ceiling.

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

• the structural collapse of wood-frame construction, or
• where roof joists support required elements of environmental separators, the excessive deformation, displacement or failure of these elements, which could lead to deterioration, which could lead to further compromised structural integrity of roofs or environmental separators.

This is to limit the probability of damage to the building.
