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 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,
- in assemblies exposed to moisture or the exterior, damage
and 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:
- compromised operation of doors or windows required for
egress in an emergency, or
- persons losing their balance, tripping or falling.
This is to limit the probability of harm to persons.
