To limit the probability that post-disaster 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, which could lead to 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.
