【摘要】 本文对一种可以同时隔离和减小水平、竖向地震作用的多维粘弹性隔减震装置的力学性能进行了研究,提出了关于该装置的力学模型,并对加与不加隔减震装置的双层大跨网壳结构进行了数值分析和比较。研究结果表明:该装置可以有效的降低结构在大震作用下的动力反应,提高结构的抗震性能。更多还原

【Abstract】 A viscoelastic multi-dimension earthquake isolation and dissipation device is designed.According to the mechanic property of viscoelastic material,a mechanic model of the device is put forward.A numerical analysis on a long-span shell with and without this device is made and the results are compared.The results indicate the device could obviously reduce the response of the structure under main earthquake and enhance the anti-earthquake ability of the structure.更多还原
