Embodiment Construction
[0027] The present invention will be further described below in conjunction with the accompanying drawings.
[0028] The segmental isolation technology belongs to the primary-secondary structure energy dissipation and vibration reduction technology, and the top floor isolation is a more practical method. By rationally designing the stiffness and damping value of the seismic isolation bearing, better performance can be achieved in the full frequency domain. Academically, the judgment standard of contour double peaks in the frequency domain transfer function is generally used. That is to say, when the ground simple harmonic acceleration with constant amplitude but variable frequency is input, the steady-state response index of the original structure reaches the maximum at its first-order natural frequency. Now, by adding the isolation layer and its damping , turning this single peak into two separate, significantly smaller, equal-height peaks is considered approximately to achie...
