In the event of a major earthquake, administrative facilities and hospitals should possess the technique to assess the structural integrity of the building themselves. In this study, relations between the damage probability for each damage state and the maximum inter-story drift angle or residual deformation angle are calculated. These relations are based on earthquake response analysis results conducted for mid-rise buildings under 115 sets of two consecutive earthquake ground motions of seismic intensity six or larger in the JMA scale. The quick inspection evaluation criteria are investigated in terms of damage probabilities based on these relations.
