Increase with the increase of x；When support meets with middle-size and small-size earthquake (PGA < 0.2g), the dynamic response of superstructure is main control
Target processed, seismic acceleration is smaller at this time, and the support relative displacement x of excitation is smaller, and support has lesser horizontal rigidity, lower
Coefficient of friction so that support shock insulation ability is more outstanding；When support meets with large-scale earthquake (PGA > 0.4g), support is with respect to position
Move as main control target, seismic acceleration is larger at this time, and the support relative displacement x of excitation is larger, the horizontal rigidity of support by
It gradually improves, coefficient of friction is also gradually increased, so that support is remarkably reinforced in the big displacement stage compared with thin tail sheep stage rigidity, effectively
Big earthquake situations condition undersetting relative displacement excessive development is controlled, while guaranteeing that superstructure dynamic response is not too big.Variable element is set
Meter can be suitable for different earthquake conditions, effectively improve tradition so that support has the adaptive ability to earthquake load
The performance of friction-pendulum shock-insulation support.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to restrict the invention, all in essence of the invention
Made any modification, equivalent replacement and improvement etc., should be included in protection scope of the present invention within mind and spirit
Within.
