[0004] Metal damper is one of the most popular dampers at present. It is usually used in various types of building structures. The working principle of metal damper is usually to increase its energy dissipation and shock absorption capacity by increasing the relative displacement. However, the current Some dampers cannot achieve energy dissipation and shock absorption under strong, moderate and small earthquakes, so the effect of shock absorption and isolation needs to be further improved

Abstract
The invention discloses a tension-compression type rubber friction metal damper. The tension-compression type rubber friction metal damper comprises a middle vertical plate, a lower end plate, an upper end plate and two energy dissipation members; the lower end of the middle vertical plate is fixed on the lower end plate, the two energy dissipation members are located on the two sides of the middle vertical plate correspondingly; each energy dissipation member comprises a side edge vertical plate, the upper end of each side edge vertical plate is fixed on the upper end plate, and a plurality of elongated through holes are formed in each side edge vertical plate; a first energy dissipation spring and a second energy dissipation spring are arranged in each elongated through hole; two rubberfriction pads are arranged between the side vertical plates and the middle vertical plate, one rubber friction pad is fixed on the side vertical plates, the other rubber friction pad is fixed on the middle vertical plate, and the side surfaces of the two rubber friction pads are in contact; and an upper side waveform energy consumption soft steel is arranged between the middle vertical plate and the bottom of the upper end plate, and lower side waveform energy consumption soft steels are arranged between the lower ends of the side edge vertical plates and the lower end plate. The damping vibration isolation effect of the damper is relatively excellent.
Description
technical field [0001] The invention belongs to the field of anti-shock and shock absorption of civil engineering, and relates to a tension-compression type rubber friction metal damper. Background technique [0002] Traditional buildings mainly rely on the deformation of the structure itself to absorb earthquake energy, and many major components are difficult to repair after damage. With the continuous advancement of anti-seismic theory, technology and methods and the development and application of more high-performance materials, people have higher and higher requirements for the anti-seismic performance of structures. After the earthquake, the loss of the whole society will be minimized. [0003] Among the several methods to realize the recoverable functional structure, the most operable is the replaceable structure. Replaceable structural components are set in the structure, and the damage of the structure is mainly concentrated in the replaceable components during stro...
