Abstract:
A type of hybrid passive control system with energy dissipation between isolated structures and adjacent structures is proposed. Compared with a single seismic isolation system, the proposed system has much stronger robustness to different frequency domain ground motions via combining isolation and damper energy consumption together. The influence of the location of the middle isolation layer on the isolation effect of the segmented isolated structure is studied by inputting different frequency domain ground motions through shaking table test. The finite element numerical simulation is compared with the experimental results. The results show that compared with other frequency-domain ground motions, the influence of long-period seismic wave on the response of the displacement and acceleration of isolated structure is more significant, which will increase the possibility of bearing overrun The overall dynamic response of the structure is the minimum when the middle isolation layer is located in the vertical middle position of the structure. The hybrid passive control system can effectively solve the problems of displacement overrun and overall overturning of high-rise seismic isolation structures, and has better control effect on the structural response under different frequency-domain seismic excitations. © 2022, Editorial Board of Journal of Vibration Engineering.
