Abstract:
Conception of elementary sliding base-isolated system(ESBS)is proposed. Using the method of modal analysis, superstructure is uncoupled into independent single DOF(degree of freedom)systems. If the mass of isolation layer is reasonably distributed to the systems, structure may be further uncoupled into ESBS with same amount of the superstructure modals. The superstructure responses can be obtained by superimposing corresponding responses of ESBS, and the isolation layer responses are identical with corresponding responses of any ESBS. The simulation analysis shows that the proposed method fully satisfies the requirement of engineering in precision, and the thought seems highly feasible in uncoupling this kind of nonlinear system.
