Intent 1:
To limit the probability of an insufficient depth
of concrete across the width of openings to provide adequate flexural
and shear capacity, and cover and bond for reinforcing steel, which
could lead to an inability to resist transverse or vertical loads,
which could lead to concrete cracking or the displacement of walls.
This is to limit the probability of compromised structural
integrity, which could lead to:
- structural failure,
- where elements support or are part of an environmental
separator, the displacement or failure of required environmental separation
elements, which could lead to the deterioration of building elements,
or
- an inability to resist expected loads, which could lead
to
- the excessive deformation or deflection 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, or
- damage to the building.
