摘　　要：提出了一种适用于柔性底层结构抗震控制的主动变刚度 /阻尼装置 ,建立了安装此装置的柔性底层结构的地震反应方程 .算例表明 ,该装置对柔性底层结构的地震反应有良好的控制作用 .此外 ,还讨论了该装置的刚度和阻尼对控制效果的影响 .In this paper, a device of active variable stiffness/damping is presented for the aseismatic control of the structures with the soft first story. The seismic response equation of the structures with the soft first story which are equipped with the device is also given. It is shown through a calculation sample that the active variable stiffness/damping device does have good control effect on the seismic response of the structures with the soft first story. In addition, the effects of the device's stiffness and damping on the control effect are also discussed.
