9.20.8.1.(2)

Intent 1:

To limit the probability of localized over-stressing and crushing of wood plates under concentrated roof or floor loads transmitted through framing elements, which could lead to inadequate load distribution, which could lead to over-stressing of hollow masonry units, which could lead to cracking of such units.

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

• structural failure of masonry construction, or
• where masonry construction 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.

Intent 2:

To exempt situations where another means of distributing roof and floor loads is provided from the application of Sentence 9.20.8.1.(1).
