Intent 1:
To limit the probability that structures with a
Discontinuity in Capacity - Weak Storey (irregularity Type 6 in Table 4.1.8.6.), which are particularly vulnerable to damage and
collapse during seismic ground motions, will be built in areas other
than low seismicity regions, which could lead to:
- the excessive deformation of, or excessive stress in,
the structural elements, which could lead to damage to the building,
or
- the excessive deformation of, or excessive stress in,
the building structure, which could lead to damage to the building,
which could impede the intended use and occupancy of the building.
Intent 2:
To limit the probability that, when built in low
seismicity regions, such structural systems will not remain elastic
when subjected to the design ground motion, which could lead to:
- the excessive deformation of, or excessive stress in,
the structural elements, which could lead to damage to the building,
or
- the excessive deformation of, or excessive stress in,
the building structure, which could lead to damage to the building,
which could impede the intended use and occupancy of the building.
