Abstract:The structure as whole in rocking or seismic isolation bearing in tension always happens in the isolated high-rise building under a strong earthquake. Regarding this problem, a simplified translationally rocking double particle model of the isolated high-rise building was established based on the principle of torsion coupling and mode mass equivalence. Employing the response spectrum method, the formulas of the seismic influence coefficients for the limit of bearing tension, damage and failure were obtained, respectively. The effect of the aspect ratio, the design surface pressure and the columns of the seismic isolation bearing on the maximum earthquake influence coefficient were analyzed. Comparing the results of the theoretical model to the shaking table model test and numerical simulation, good agreement was obtained. Meanwhile, the comparison between the aspect ratios of 3, 4 and 5 also showed that the theoretical model was consistent well with numeric simulation results. The research results can provide reference for the design of the high-rise isolated structure.
