In this research lead core rubber bearing (LCRB) seismic isolator is designed such that the available period (4secs) of it is increased to (6secs), low period important structures (hospital, school, and similar structures) equipped with this type isolator has exhibited safer behavior at least around extremum range of the strong and long period earthquake excitations and proposed for related applications. The LCRB6 seismic isolation system and the hospital building resting on isolation system has been modeled in LS-DYNA finite element software and analyzed using various strong and long period ground motions, related response results of the structure have been presented.
