However, the hydraulic parallel-link vertical seismic isolation device, which was intended to be used in combination with the system, was removed from the experiment due to damage caused by operator error during a trial run. Shaking tests were conducted using seismic waveforms such as the 1995 Hyogoken-Nanbu Earthquake (JR Takatori record). As a result, the system successfully reduced horizontal accelerations to less than one-tenth of their original values during strong ground motions, achieving the target performance.
