Bending-shearing coupling type metal damper
The invention discloses a bending-shearing coupling type metal damper which comprises a shearing steel plate, a bending steel plate, an upper end plate and a lower end plate. Cross section optimization design is performed on the shearing steel plate and the bending steel plate according to distribution of shearing force and bending moment, so that all cross sections of the steel plates yield simultaneously, and upper and lower end plates are perforated to facilitate bolt connection. The shearing steel plate and the bending steel plate are welded with the upper and lower end plates. The bent steel plates are symmetrically distributed on the two sides of the shearing steel plate, and the effect of preventing the shearing steel plate from buckling out of the plane and losing stability is achieved. An energy dissipation mechanism of the damper comprises bending deformation of the bent steel plate and shearing deformation of the shearing steel plate, and therefore the damper has high energy dissipation capacity. And moreover, by reasonably designing parameters such as sizes and materials of the bent steel plate and the shear steel plate, the damper can have a relatively large yield stiffness ratio, so that residual deformation is effectively reduced. The device has the advantages of being simple in structure, easy to machine, easy to assemble and disassemble, high in energy dissipation capacity, high in deformation recovery capacity and the like.
本发明公开了弯剪耦合型金属阻尼器，包括剪切钢板、弯曲钢板和上下端板。剪切钢板和弯曲钢板分别根据剪力和弯矩的分布进行截面优化设计，使钢板的所有截面同时屈服，上下端板开孔以便螺栓连接。剪切钢板和弯曲钢板均与上下端板焊接。弯曲钢板对称分布在剪切钢板的两侧，起到防止剪切钢板发生平面外屈曲失稳的作用。阻尼器的耗能机制包括弯曲钢板的弯曲变形和剪切钢板的剪切变形，因此具有较高的耗能能力；并且，通过合理设计弯曲钢板和剪切钢板的尺寸和材料等参数，可使阻尼器拥有较大的屈服后刚度比，从而有效地减小残余变形。本发明具有构造简单、易于加工、易于装卸、耗能能力强和恢复变形能力强等优点。
