碟形弹簧竖向减震体系的分析与研究
A study on vertical seismic isolation system with disk spring
【摘要】 对碟形弹簧竖向减震体系利用时程分析方法对其进行动力分析,并输入不同场地、不同频谱的地震波考察其减震效果,验证了碟形弹簧在合理控制其刚度的前提下可以起到有效减小竖向地震的作用。
【Abstract】 In this paper, vertical seismic isolation system with disk spring is analyzed by using time-history analysis method. Under seismic waves of different frequency spectra, seismic responses of the vertical isolation system are calculated for different sites, and its seismic isolation effect is examined. It is approved that the disk spring with reasonable stiffness can decrease efficiently vertical seismic response.
