A plurality of first bolts are arranged on the straight section of the metal energy dissipation element, and the two ends of the above-mentioned pair of T-section steel materials are fixedly connected by the first bolts; the straight section of the metal energy dissipation element is connected to the connector by the second bolt; The invention has clear energy consumption mechanism, simple structure, low cost, convenient replacement, flexible use and strong applicability, can effectively improve the seismic performance of building structures, and can also reduce the wind vibration response of high-rise and super high-rise structures, and is also suitable for assembly The rapid construction of the building structure has a good market promotion and application prospect.

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
