The control performance in active control system can be drastically deteriorated when the modeling errors and the uncertainties existing in the seismic disturbances are disregarded in the designing stage. It can even throw the system into unstable phase, resulting in out of control against the excitations. The purpose of the study is to investigate the control effectiveness of a non-linear control system called sliding mode controller in cooperation with a base-isolated system subjected to the three seismic excitations selected from the FFT analysis. In results, the relative displacements in the isolated floor and story drift were reduced more than 90%. The absolute acceleration of the top floor was controlled in 54% or more, showing excellent
controlling behaviors in all three different excitations.
