Thirdly, a new type base isolation system, i. e., slide-limited friction base isolation system is presented in this paper. Based on this system, harmonic and subharmonic periodic response of S-LF subjected to harmonic motion is investigated by using Floquet theory. Dynamic response of sliding structure subjected to earthquake ground motion is calculated with a precise high order direct integration method, and the numerical results are presented in terms of maximum acceleration response spectra of supcrstructure and maximum sliding displacement response spectrum. By comparison with isolating effects of pure-friction base isolation system and resilient-friction base isolation system , it shows that the isolating characteristic of S-LF is superior to P-F and R-FBI. Through analyzing an engineering example, it is observed that the maximum inter-storey shear force and absolute acceleration of sliding structure to earthquake ground motion are very different from those of traditional structures.
