Tensile variable-rigidity vertical seismic isolation support and using method thereof
The invention discloses a tensile variable-stiffness vertical seismic isolation support and a using method thereof, and belongs to the field of shock absorption and isolation of engineering structures. The support comprises a first connecting plate and a second connecting plate, and a viscous damper used for absorbing seismic energy is arranged between the first connecting plate and the second connecting plate; a plurality of variable rigidity assemblies are further arranged in the circumferential direction of the viscous damper; when the viscous damper is subjected to vertical acting force, the viscous damper can effectively consume energy, the variable-rigidity assembly converts vertical displacement of an upper structure or equipment into horizontal displacement, and the rigidity of the variable-rigidity assembly is far smaller than that of the structure, so that the purposes of prolonging the vertical vibration period of the structure and reducing earthquake response are achieved. By the adoption of the support, nonlinearity of the ratio of vertical deformation of the support to horizontal deformation of the variable-rigidity assembly can be achieved, the support has higher rigidity during large deformation, variable rigidity is achieved, and vertical displacement of an upper structure during large earthquakes can be reduced; the support is simple in structure and principle, capable of effectively achieving vertical shock insulation, convenient to implement, operate and maintain and good in application and popularization value.
本发明公开了一种抗拉变刚度竖向隔震支座及其使用方法，属于工程结构减震隔震领域，本支座包括第一连接板和第二连接板，中间设置用于吸收地震能量的粘滞阻尼器；粘滞阻尼器周向上还设置了多个可变刚度组件；当受到竖向作用力时，粘滞阻尼器能够有效耗能，可变刚度组件将上部结构或设备的竖向位移转变为水平位移，因可变刚度组件刚度远小于结构刚度，从而实现延长结构竖向振动周期，减小地震反应的目的；采用本支座能够实现支座竖向变形和可变刚度组件水平变形之比的非线性，支座在大变形时具有更大的刚度，实现变刚度，可减小上部结构大震时的竖向位移；本支座的结构和原理简单，能够有效实现竖向隔震，便于实施和运维，具有良好的推广应用价值。
