安全を確保する ”AMD制震システム” To successfully strike a balance between security and livability, an active mass damper system containing two master dampers, has been installed on the topmost floor of the building. All the other floors contain hysteresis and viscous damping devices within their structure. These can cope with both the severe swaying caused by large earthquakes (200-300 gals acceleration response spectrum of the hysteresis theory) or the lesser swaying resulting from strong winds (20-30 gals acceleration response spectrum). The building has been constructed to withstand an earthquake of seismic intensity 7 on the Japanese scale and a maximum velocity of 50centimeters/second. Copyright (C) 2005 Homat Viscount.
