Abstract

The invention discloses a metal high-efficiency energy consumption damper, which comprises a 1st-5th energy-consuming rod elements made of mild steel and a 1st-4th node plates, wherein the first energy-consuming rod element, the second energy-consuming rod element, the third energy-consuming rod element and the fourth energy-consuming rod element are connected end-to-end to form a diamond shape and are arranged with longitudinal symmetry and bilateral symmetry, the included angle of the first energy-consuming rod element and the second energy-consuming rod element is obtuse angle, the includedangle of the third energy-consuming rod element and the fourth energy-consuming rod element is an obtuse angle, and the fifth energy-consuming rod element is as a diagonal of the long-axis of the diamond. The fifth energy-consuming rod element is as an up-and-down diagonal of the diamond. According to the invention, the damper has the advantages of energy consumption component capable of yieldingas soon as possible under the action of earthquake, generating plastic deformation and greatly consuming seismic energy, no failure caused by excessive plastic deformation due to large energy consumption, and achieving the purpose of permanent seismic absorption. The diamond structure is the key of high efficiency energy consumption.

Description

technical field [0001] The invention relates to an energy-dissipating and shock-absorbing device, in particular to a metal high-efficiency energy-dissipating damper. Background technique [0002] Conventional metal dampers are metal blocks with lower yield points connected to the building structure through additional support rods to play the role of energy dissipation and shock absorption. When the building structure is excited by the earthquake, the additional support rods act on the conventional metal damper. When the conventional metal damper yields, it will produce plastic deformation, thereby consuming the seismic energy of the structure to achieve the purpose of shock absorption. However, before the conventional metal damper yields, the conventional metal damper will produce elastic deformation and will not consume earthquake energy. On the contrary, due to the application of elastic components in the building structure, the rigidity of the building structure will be i...
