The purpose of this study is to identify the dynamic property of the structure, and to construct the procedure to obtain the basic structural information for the seismic diagnosis based on the microtremor observation of buildings. MOESP is the basic method in the subspace identification, which enables us to simulate the M-C-K model of buildings through the input and output data obtained by the real observations. In this study the basic dynamical characteristics of the buildings such as natural period and damping factor are evaluated by MOESP and Pi-MOESP method which developed MOESP to reduce the noise effect of the data by using auxiliary variables.
