Friction pendulum support
The invention belongs to the technical field of engineering seismic mitigation and isolation, and provides a friction pendulum support which comprises an upper seat plate, a middle seat plate and a lower seat plate, the middle seat plate is arranged between the upper seat plate and the lower seat plate, the upper end and the lower end of the middle seat plate are both curved surfaces, and the convex surfaces of the two curved surfaces face the same direction; the lower end surface of the upper seat plate is matched with the upper end surface of the middle seat plate in shape; and the upper end surface of the lower seat plate is matched with the lower end surface of the middle seat plate in shape. The original friction pendulum support design theory is broken through, the shapes of the upper end face and the lower end face of the middle seat plate are optimized, the convex faces of the upper end face and the lower end face of the middle seat plate face the same direction, and through the arrangement, under the same design parameters (such as bending rigidity, shock insulation period, displacement and friction coefficient), the overall height is obviously reduced, and the weight is lighter. Therefore, under some extreme design parameters which are difficult to design or cannot be realized by the conventional structure design, the method can be easily realized.
本发明属于工程减隔震技术领域，提供一种摩擦摆支座，包括上座板、中座板和下座板，中座板设置在所述上座板和所述下座板之间，所述中座板的上下两端均为曲面，并且两个曲面的凸面朝向一致；所述上座板的下端面与所述中座板的上端面形状吻合；所述下座板的上端面与所述中座板的下端面形状吻合。本发明突破了原有的摩擦摆支座设计理论，对中座板的上下端面形状进行优化，使中座板上下端面的凸面朝向一致，通过这种设置，使其在同样的设计参数(如屈后刚度、隔震周期、位移、摩擦系数等)下，整体高度明显降低，重量也更轻。因此，在一些现有常规结构设计较为困难或者无法实现的较为极端的设计参数下，本发明也能够轻松实现。
