Multi-stage energy consumption connecting piece
The invention discloses a multi-stage energy consumption connecting piece. According to teh Multi-stage energy consumption connecting piece, trusses are arranged on the upper plate face and the lower plate face of a buckling core plate, so that the slenderness ratio of the buckling core plate is reduced, it is guaranteed that the buckling core plate is not unstable, and therefore it is guaranteed that the buckling core plate can conduct buckling energy consumption; sleeves are arranged outside the trusses, so that deformation of the trusses in the radial direction of the sleeves is restrained to a certain extent, and buckling energy consumption of the trusses can be achieved; when the earthquake action is too large, all energy is dissipated through the combined action of the buckling core plate and the trusses; and the first connecting end and the second connecting end of the connecting piece are fixed to an external wall body or a beam, when the connecting piece is axially stressed, the second connecting end extrudes or tensions the second connecting rod to rotate, and meanwhile, the first connecting end and the first connecting rod can rotate relative to each other, so that the middle part of the connecting piece can integrally rotate to generate rotational friction energy consumption, and under smaller earthquake action, the purpose of energy consumption is achieved through rotation friction.
本发明公开了一种多级耗能连接件，其通过在屈曲核心板的上下板面设置桁架，以此来减小屈曲核心板的长细比，保证屈曲核心板不会失稳，从而保障其能够屈曲耗能；桁架外设置套筒对桁架在套筒径向上的形变产生一定的约束，使桁架能够实现屈曲耗能；当地震作用过大时，通过屈曲核心板和桁架共同作用将所有的能量耗散掉。其第一连接端和第二连接端与外部墙体或梁固定，在轴向受力时，第二连接端挤压或者张拉第二连杆使其旋转，同时第一连接端和第一连杆可相对彼此旋转，因而连接件的中间部分会整体旋转，产生转动摩擦耗能，在较小的地震作用下，通过转动摩擦达到耗能的目的。
