000019879 520__ $$2eng$$aSeismic isolation is a popular type of seismic protective system in which the dominant resonant frequencies of the structure are moved to the lower frequency range of the spectrum to protect the structure and its contents from ground accelerations. Isolating the structure is an effective way to attenuate vibration of the superstructure when subjected to earthquakes with significantly higher dominant frequencies, but at the same time this approach increases the vulnerability of the structure to long-period long-duration earthquakes. This paper proposes the application of the connected control method to provide isolation performance for long-period long-duration earthquakes without compromising the isolation at higher frequencies. An analytical model is presented to demonstrate through a frequency domain analysis that the connected control method can be applied to adjacent base isolated buildings to provide reduction in the isolator resonant peaks while not increasing the attenuation of the responses, thus protecting the isolated buildings from long-period long-duration earthquakes without affecting the performance of the isolation to higher frequency excitation.
