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.
This is to limit the probability of compromised structural
integrity, which could lead to:
- the structural collapse of the superstructure or the
foundation, or
- for environmental separators or construction that supports
environmental separators, 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:
- the space being unsuitable for its intended use,
- compromised operation of windows or doors, or
- damage to the building.
Intent 2:
To expand the application of Part 4, where construction
is in high wind and seismic regions.
