Intent 1:
To limit the probability of:
- inadequate corrosion resistance, which could lead to
the corrosion of metal ties,
- an inadequate cross-sectional area, or
- an inadequate shear area through the mortar.
This is to limit the probability of:
- buckling failure of metal ties under lateral loads,
- tensile failure of metal ties under gravity loads, and
- failure of the bond between mortar and metal ties under
lateral loads.
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, 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.
