Fabricated graded energy dissipation bridge support
The invention discloses a fabricated graded energy dissipation bridge support. The support comprises a support body and a detachable fabricated energy dissipation assembly, wherein a connecting plate is arranged on the side face of the bottom of the support body; the energy dissipation assembly comprises a sliding limiting plate, and at least one arc-shaped energy dissipation structure is fixed to the side face of the sliding limiting plate; the energy dissipation assembly is symmetrically fixed to the two sides of the support body through shear bolts; the connecting plate and the energy consumption assembly are connected through a detachable connecting shaft; the connecting plate is provided with a sliding groove parallel to the long edge of the connecting plate, the sliding limiting plate is provided with a connecting hole matched with the sliding groove, and the sliding limiting plate is assembled and connected with the connecting plate through connecting shafts; the sliding limiting plate can move freely along the sliding groove. By arranging a limiting energy consumption device between a bottom basin and an upper seat plate of the support body, the support is limited and restrained under static working conditions of automobile loading, pulsating wind and the like, and the displacement of a main beam is reduced; under the action of a rare earthquake dynamic working condition, the shear bolts are sheared off, the arc-shaped energy dissipation structure generates plastic deformation, so that damping and energy dissipation functions of the support are achieved.
本发明公开了一种装配式分级耗能桥梁支座，其包括支座主体和可拆卸装配化的耗能组件，支座主体底部侧面设置连接板。其中耗能组件包括滑动限位板，滑动限位板侧面固定有至少一个弧形耗能结构；支座主体两侧通过剪力螺栓对称固定耗能组件；连接板与耗能组件通过可拆卸连接轴进行连接。连接板上设有与其长边平行的滑槽，滑动限位板设置与滑槽配合的连接孔，其通过连接轴与连接板装配连接；滑动限位板可沿滑槽作自由运动。本方案通过在支座本体的底盆与上座板间设置限位耗能装置，实现支座在汽车荷载、脉动风等静力工况作用下的限位约束，减小主梁的位移；在罕遇地震动力工况作用下，剪力螺栓被剪断，弧形耗能结构发生塑性变形，实现支座的减震耗能功能。
