Hybrid shake table testing method: Theory, implementation and application to midlevel isolation

A 2 m by 6 m unidirectional shake table was constructed at the University of California, Berkeley and combined with a real‐time hybrid simulation system creating a hybrid shake table. A series of tests were carried out to examine the viability of real‐time hybrid simulation techniques to perform experimental simulations of buildings with midlevel seismic isolation. The isolation system and superstructure were physically tested on the table …
