Vibration behaviors of an existing high-rise building are discussed on the basis of response observation and measurements. The seismic performance is analytically investigated assuming severe earthquakes in the future. The investigated building is a 30-story RC rahmen structure constructed in 1988 at the site of 17km to the south-southwest from Tokyo. Structural damage to the building caused by ground motions had not been observed during 19 years of the earthquake response observation since the completion of the building. However, it was confirmed that fundamental periods of the building elongated with the passage of time. A slight damage to non-structural walls of the building caused by the Great East Japan Earthquake 2011 has been observed. The results of microtremor measurement show that any damage might have occurred to the structural members of the building because of the elongation of the fundamental periods, which was caused by the earthquake. The non-linear response analyses indicate that any damage might have also been generated in the structural members. The largest story drift angle will be approximately 1/100rad. according to the analyses using the assumed ground motion obtained by amplifying the long-period component.
