| Abstract: | In this paper, the computation and the equation of motion for base isolation system using roller bearings with restoring property are presented. A base isolated rigid body system is assumed to be subjected to steady harmonic excitation and the response is to be analyzed, The optimum stiffness of the isolated layer of the multistory masonry building with different damping ratios is suggested. Response spectrum of isolation system is proposed. |
