Sentence 9.20.11.1.(4)

Intent 1:

To limit the probability of inadequate strength of floor or roof joists to resist lateral loads, which could lead to inadequate anchorage of floor or roof assemblies to masonry walls, which could lead to inadequate lateral stiffness, which could lead to an inability to resist lateral loads or inadequate distribution of gravity loads, which could lead to cracking or buckling.

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.
