Abstract

The invention relates to a metal shear friction composite energy dissipation device. The metal shear friction composite energy dissipation device comprises a friction assembly and a shear assembly. The metal shear friction composite energy dissipation device is connected between a first interlayer structure and a second interlayer structure. The friction assembly and the shear assembly are fixedlyconnected. When shear energy exists between the first interlayer structure and the second interlayer structure, the shear energy can be transmitted to the friction assembly and the shear assembly. The friction assembly can absorb the shear energy through internal friction. A first connecting plate and a second connecting plate can further move relative to each other to enable a first core plate to be deformed elastically and deformed plastically to absorb the shear energy. The metal shear friction composite energy dissipation device can effectively absorb the shear energy between the first interlayer structure and the second interlayer structure by three modes of friction, elastic deformation and plastic deformation, and the interlayer displacement between the first interlayer structure and the second interlayer structure is reduced.

Description

technical field [0001] The present application relates to the technical field of detection, in particular to a metal shear friction composite energy dissipator. Background technique [0002] The development of today's buildings tends to be more and more tall, and the frame structure composed of steel members, composite members or reinforced concrete members is a structural form that is often used in buildings. In order to make the building structure have a strong ability to resist damage from external forces such as earthquakes or wind loads, it is often necessary to add energy-dissipating components to the frame structure. [0003] At present, the sliding displacement of the common friction metal shear friction composite energy dissipator is generally 1-2mm. For general high-rise or all-steel structure buildings, the interstory displacement of the structure can reach 6-10mm under small earthquakes. The maximum value of the horizontal earthquake influence coefficient of mo...
