In the Mw9.0 2011 Tohoku, Japan, earthquake, high-rise buildings located in Tokyo and Osaka, far from the source zone, were shaken by long-period seismic ground motion. In this study, vibration characteristics of a high-rise building located in Osaka Bay coast were investigated using seismic records obtained in the 2011 Tohoku earthquake and other events. The natural periods, participation functions and damping ratios were identified based on the fitting of theoretical transfer functions by observed Fourier spectral ratios. Through this identification, the change of modal parameters of the building in time due to structural nonlinearity and seismic retrofitting were recognized. Finally, the prediction of seismic response due to the scenario Nankai-Trough earthquake was performed.
