Rubber-sliding system support with multi-stage shock isolation and shock isolation effect calculation method thereof
The invention provides a rubber-sliding system support with multi-stage shock isolation. The rubber-sliding system support comprises a laminated damping body (1), an upper sliding system (2) and a lower sliding system (3) are slidably connected to the upper surface and the lower surface of the laminated damping body (1) respectively, and the dynamic friction coefficient mu<1> of the upper slidingsystem (2) is smaller than the dynamic friction coefficient mu<2> of the lower sliding system (3). The invention further provides a calculation method of the shock insulation effect of the rubber-sliding system support with the multi-stage shock insulation effect. By arranging the laminated damping body, the upper sliding system and the lower sliding system, the multi-stage shock insulation function is achieved under the condition that the plane area is not changed; the shock insulation effect of the laminated damping body is mainly achieved during small earthquakes; when the earthquake magnitude is increased, the horizontal earthquake inertia force is increased, so that the upper sliding system starts to work; and when a rare major earthquake occurs, the lower sliding system begins to work, meanwhile, the laminated damping body is protected, and when the support system plays a role together, the damage effect of earthquake oscillation on an upper structure is greatly reduced.
本发明提供了一种多级隔震的橡胶‑滑移体系支座，包括叠层减震体(1)，所述叠层减震体(1)的上表面和下表面分别滑动连接有上滑移体系(2)和下滑移体系(3)，所述上滑移体系(2)的动摩擦系数μ1小于所述下滑移体系(3)的动摩擦系数μ2。本发明还提供了一种多级隔震的橡胶‑滑移体系支座的隔震效果的计算方法。本发明通过设置叠层减震体和上、下滑移体系，在平面面积不变的条件下实现多级隔震功能：小震时主要发挥叠层减震体的隔震作用；当震级增大，水平地震惯性力的增加使得上滑移体系开始工作；罕遇大震时，下滑移体系开始工作，同时对叠层减震体起到保护作用，支座体系共同发挥作用时将大大减轻地震动对上部结构的破坏作用。
