Seismic performance of the existing mid-to-low-rise apartment houses of reinforced concrete frame structure were discussed by the current standard for seismic diagnosis and several problems were pointed out through the comparison of the results of seismic diagnosis with the observed damage conditions on reinforced concrete apartment houses due to the resent earthquakes, Resultantly, the followings were made clear. 1. Due to the secondary seismic diagnosis of the analyzed 17 apartment houses, the resultant Seismic Index of Structure (Is) values are almost among 0.3 and 0.5, and several are slightly less than the value of the judgment index of seismic performance (Iso)=0.6. 2. Never the less above results, it was made clear that damages to the mid-to-low-rise apartment houses caused by recent earthquakes are almost slight or none. 3. Is indices of the 6 buildings out of the 17s become larger and exceed the value of Iso by modifying the evaluation method of columns with side walls and considering site ground condition to the ground index G1.
