Intent 1:
To limit the probability of inadequate support for
ties, which could lead to the excessive flexing of ties under lateral
loads, which could lead to 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.
