In this paper, dynamic properties identification on damage evolution of 6 story reinforced building is shown through shaking table test. Two types of identification are tried. One is a) identification using the data during damage evolution and the other is b) identification using the data of before and after damage. From the results of a), natural frequency and story stiffness decreases and damping ratio increases as amplitude increases, and natural frequency and story stiffness tend to be smaller and damping ratio tends to be larger during principal motion. Tendency of identified story stiffness from b) is consistent with visual inspection. Minimum identified stiffness from a) agrees with the results from push over analysis.
