Intent 1:
To limit the probability of an insufficient thickness
of concrete in walls, insufficient bearing of supported walls, or
eccentric loads on the wall, which could lead to an inadequate resistance
to lateral earth pressure or an inability to support transverse or
gravity loads, which could lead to concrete cracking.
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.
