... ake responses by simuiation analysis , this e日rIhquake response ge 鯛 eratQr system is applicd into vibration tests ofthe 血ll − scale struoture . Observed acce 且 eration responses ofthe 血ll − sca 皇 e structure in these tests are oompared with Galculated responses under Ihe earthquakes . Rcsults demonstrate the accuraoy and validity ofthe earthquake response gcnerator system . It is ernphasized that by rnaking use ofthis exper 重 mental system , Ihe Gontrol pcrfbrmanco ofseismic response control on full − scale struGtures can be exar 垣 ned like shaking tablo tests .
