Abstrakt:

(1) Research background: The aim of this study was to explore the seismic response of vertically irregular high-rise buildings using a double-layer isolation system. (2) Methods: A 24-story vertically irregular high-rise frame-shear wall structure was designed, and the finite element model of the double-layer isolation structure was established, as well as the models of the seismic structure, the foundation isolation structure, and the story-separated seismic structure. A dynamic time–history analysis of these models under rare ground motion was carried out. (3) Results: The double-layer isolation system has the best isolation effect, followed by the foundation isolation structure, and finally the interlayer structure. The double-layer isolation system can increase the natural vibration period of the structure by 1.25 times, reduce the displacement angle of the layer by about 74.3%, reduce the acceleration of the top layer by about 82.3%, reduce the base shear force by about 59.68%, reduce the overturning moment of the bottom layer by about 68.89%, and reduce the torsion angle of the top layer by about 89.68%. (4) Conclusions: The double-layer isolation system can effectively reduce the overall seismic response of the structure and effectively control the torsional response of the structure, which makes it feasible for application.
