Modal analysis and system identification method via ARMAX model are applied to two steel frame high-rise buildings by using recorded earthquake responses. The structure is analyzed in a single-input single-output(SISO) dynamic system, and the natural frequencies and damping ratios of the two buildings are estimated by two methods. There is no big difference between the results by two methods. System identifications by modal analysis are depend on the coherency of the obtained transfer functions, and estimated results by method via ARMAX model are depend on the degree of freedom of the analyzed modeling parameters. キーワード（英）： - 記事区分： - 区分 　　　委員会論文集
