Seismic Response and Hysteric Performance Analysis in Different Base Isolated Structures

Abstract:

Firstly, the motion equation for parallel composite isolation system was formulated. Then, taking system with seven degree of freedoms for an illustrative example, the nonlinear dynamic responses of ordinary aseismic system, isolation system with friction sliding bearings, isolation system with laminated rubber bearings and parallel composite isolation system with the above combined bearings were calculated. Finally, the seismic responses of the above four structures were compared and discussed comprehensively and systematically, and the hysteretic performance of isolated floor was investigated. The results show that the isolation effect of isolated systems compared with the ordinary aseismic system is very notable and the hysteretic energy dissipation performance of isolated structures is excellent.
