Combined arc-shaped steel plate damper
A main energy dissipation component of the combined arc-shaped steel plate damper is an arc-shaped mild steel plate, and after the arc-shaped mild steel plate is welded and combined with a rectangular steel plate, the upper part and the lower part of the arc-shaped mild steel plate are welded with a rectangular sleeve; the middle part of the guide pipe is connected with a rectangular guide pipe arranged in the rectangular sleeve; the connecting steel plates are welded to the two sides of the rectangular guide pipe and the rectangular sleeve and used for being connected with a structure. According to the damper, the two arc-shaped steel plates are combined through the connecting mode, half of the arc-shaped steel plates are always kept in a pulled state, the half of the arc-shaped steel plates are always kept in a pressed state in the energy consumption work, and the defect that the pressed bearing capacity of a single arc-shaped steel plate is smaller than the pulled bearing capacity due to the fact that the single arc-shaped steel plate is bent initially is overcome. According to the damper, the yield displacement and the maximum restoring force of the damper can be controlled by adjusting the parameters such as the initial bending rate, the thickness and the width of the arc-shaped steel plate, manufacturing, construction, overhauling and replacement after earthquake damage are convenient, the damper can be applied to various structural energy dissipation and vibration reduction systems, and the anti-seismic capacity of an engineering structure is greatly improved.
本发明公开了一种组合式弧形钢板阻尼器，其主要耗能构件为弧形软钢板，通过与矩形钢板焊接组合后其上下部分与矩形套管相焊接；中部与内置于矩形套管中的矩形导管相连接；连接钢板焊接与矩形导管与矩形套管两侧，用于与结构相连接。该阻尼器通过此种连接方式将两块弧形钢板相组合，在耗能工作中始终保持弧形钢板一半处于受拉状态，一半处于受压状态，弥补了单一弧形钢板由于存在初始弯曲导致其受压承载力小于受拉承载力的缺点。该阻尼器可通过调整弧形钢板的初始弯曲率、厚度、宽度等参数来控制其屈服位移与最大恢复力，且便于制作，施工，检修以及震后损坏更换，可应用于各种结构消能减振体系中，并极大地提高工程结构的抗震能力。
