Passive isolation system may not work well if seismic excitation is other than the design earthquake. Active isolation system may work well under different earthquakes but it is expensive. Hence, semi-active isolation is a solution. In this paper, the “leverage-type stiffness controllable isolation system”(LSCIS) with simple control algorithm is studied. The algorithm is designed under a far-field earthquake but the LSCIS device also works well under various intensities of the far-field and near-fault earthquakes. Both structural base shear and LSCIS displacement are suppressed. |
