Sentence 9.20.9.4.(2)

Intent 1:

To limit the probability that the performance of the ties will fall significantly below expectations, with respect to:

• corrosion resistance,
• resistance to buckling, tensile failure and withdrawal under compression and tensile loads, and
• transferring lateral loads from one wythe to another.

This is to limit the probability of inadequate load distribution among the wythes of multiple-wythe masonry walls, which could lead to an inability to resist transverse or vertical 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.
