摘要
对原有变刚度滞变-摩擦隔震支座进行了改进,提出一种多级变刚度滞变耗能器,并进行了初步的试验研究。在此基础上,对一纯框架结构(1:5)模型进行了耗能与隔震的联合控制试验研究,试验结果表明,采用这种联合控制技术能降低不同大小地震下的结构反应,具有很强的适应性。
In this paper, the stiffnesvariable hystereticfriction isolation support is improved, and a kind of energydissipation device with multilevel variablestiffness is presented. At the same time, the preliminary test research for the energy dissipation device is conducted. On these bases, energydissipation and earthquakeisolation test investingations is carrie out with a 1/5 framework structure model without wall. The results of the test show that it is able to reduce the responses of the structure under different intensities and has a great adaptation for the control ling seismic response of the structure.
