The full-scale reinforced concrete seven-story structure, once tested by the pseudo-dynamic test method, was repaired and tested again. This paper presents the response, the restoring force characteristics and the observed damage during the post-repair test. Major findings from the test are as follows ; 1) Since the repair works were applied only to the critical regions of the structure, the structure's stiffness was not perfectly recovered. The repaired structure with such reduced stiffness showed that : (1) when the amplitude of input acceleration was of low level, the response was quite different from that of the intact structure, however, (2) when the amplitude of input acceleration was high enough to render the structure to reach the yielding, both response became close. 2) The shear wall failed in shear when subjected to rectangular-distribution loads although it behaved in a very ductile manner when subjected to inverted-triangular-distribution loads. Observed shear strength of the wall was about 20 % greater than the computed one.
