Metal energy dissipation damper

Abstract

The invention provides a metal energy dissipation damper comprising a connecting piece and a metal energy dissipation element. The connecting piece is fixedly connected with a building, the metal energy dissipation element is connected with the building by the connecting piece, and the energy dissipation element consists of a pair of T-shaped section steels after the middle portion is relatively bent in a welding connection. The medal energy dissipation element is divided into a straight-line segment and a circular segment, and the two ends of the circular segment are separately connected withthe building by the straight-line segment and the connecting piece. The straight-line segment of the metal energy dissipation element is provided with a plurality of first bolts, and the two ends ofthe pair of the T-shaped section steels are in a fixed connection by first bolts; the straight-line segment of the metal energy dissipation element is connected with the connecting piece by a second bot. The metal energy dissipation damper is explicit in energy dissipation mechanism, simple in structure, low in cost, flexible in using, strong in applicability. The seismic behavior of the buildingstructure is enhanced efficiently, the wind-induced dynamic response of the high-rise and super high-rise structure also can be reduced, meanwhile, the metal energy dissipation damper applies to the rapid construction of an assembled building structure, and marketing application prospects is good in generalization.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, in particular to a metal damper utilizing bending deformation to consume energy, which can be applied to the field of vibration control of building structures. Background technique [0002] Adding energy-dissipating components in the building structure can make the building structure have a strong ability to resist damage from external forces such as earthquakes or wind loads. Common energy-dissipating components include friction dampers, viscous (elastic) dampers, magneto-rheological dampers, and metal energy-dissipating dampers. Among them, the metal energy-dissipating damper is an energy-dissipating shock-absorbing device with superior energy-dissipating performance, convenient manufacture, low cost, and easy replacement. purpose of shock. It can be used as an energy-dissipating unit or a limiting device in conjunction with a seismic-isolation support or a seismic-isolation system,...

AI Technical Summary

Problems solved by technology

[0003] At present, there are roughly two types of metal energy-dissipating dampers. One is that the damper is made of steel with a low yield point, and it mainly uses the axial tension or pressure of the damper to dissipate energy. The damper made of point steel increases the production cost, and its structure is not simple, which increases the engineering cost and is not conducive to popularization and application; the other is a metal energy-dissipating damper made of ordinary steel. Complicated, some need to be used with support. For example, the patent No. ZL201010114545.7 discloses an anti-tension and compression yield metal bending energy-dissipating damper, which belongs to this case
