This paper investigated the accuracy of the seismic response characteristics of building evaluated by the autoregressive exogenous model (ARX), the subspace state-space system identification method (4SID), and the complex mode indicator function method (CMIF). First, the accuracies of the natural frequency, the damping ratio, and the specific mode shape identified by the three methods were compared based on linear seismic response analysis. Then, the dynamic characteristics of the SRC building were identified by the abovementioned three methods using the strong motion records of the 2011 off the Pacific coast of Tohoku Earthquake and its aftershock. From the comparison of these identified results, the characteristics of these methods were estimated.
