Intent 1:
To limit the probability of inadequate lateral support
for wythes of masonry walls, which could lead to wythes and masonry
walls being unable 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 excessive deflection or vibration of floors.
This is to limit the probability of:
- for floors and elements supporting floors, persons losing
their balance, tripping or falling, or
- the compromised operation of doors or windows required
for egress in an emergency.
This is to limit the probability of harm to persons.
