Especially, it is clarified that response amplification of upper structures of the isolation story is caused by modal coupling effects between modes of vibration on upper and lower structures. In this paper, results obtained by the eigenvalue analysis and random vibration analysis with frequency response function are as follows: 1) Modal coupling effects are caused by vibration modes on which isolation story is not deformed, and 2) Modal coupling effects amplify earthquake response of upper structure and decrease a effect of seismic isolation, however modal coupling effects do not greatly influence the story deformation of isolation story. 000010539 540__ $$aText je chráněný podle autorského zákona č. 121/2000 Sb. 000010539 653__ $$aSeismic Isolation, Mid-story Isolation, Base Isolation, Eigenvalue Analysis, Modal Coupling Effect, Frequency Response Function 000010539 7112_ $$a14th World Conference on Earthquake Engineering$$cBejing (CN)$$d2008-10-12 / 2008-10-17$$gWCEE15 000010539 720__ $$aKobayashi, Masahito$$iKoh, T. 000010539 8560_ $$ffischerc@itam.cas.cz 000010539 8564_ $$s1600677$$uhttps://invenio.itam.cas.cz/record/10539/files/05-01-0230.pdf$$yOriginal version of the author's contribution as presented on CD, Paper ID: 05-01-0230. 000010539 962__ $$r9324 000010539 980__ $$aPAPER
