Intent 1:
To limit the probability of:
- an inability to resist expected wind and seismic loads,
which could lead to overturning, lifting or sliding of the superstructure
off the foundation, and
- where the superstructure is required to provide lateral
support for the foundation, an inability to resist expected lateral
earth pressure loads, which could lead to:
- cracking or differential movement of the foundation,
or
- compromised structural integrity of the foundation,
which could lead to deflection or deformation of the superstructure.
For floors and constructions supporting
floors, this is to limit the probability of:
- compromised structural integrity, or
- for exterior floors or environmental separators supporting
a floor, the excessive deformation, displacement or failure of required
environmental separation elements, which could lead to deterioration,
which could lead to further compromised structural integrity.
This is to limit the probability of excessive movement,
vibration or deflection of floors, which could lead to negative effects
on the psychological well-being of persons.
