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 of masonry construction,
- where masonry construction is part of an environmental
separator, the displacement or failure of required environmental separation
elements, which could lead to deterioration, or
- an inability to resist expected loads, which could lead
to:
- the excessive movement or deformation of walls, or
- the excessive deflection or vibration of floors.
This is to limit the probability of:
- the space being unsuitable for its intended use,
- compromised operation of windows or doors, or
- damage to the building.
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).
