Abstract

The invention provides a metallic damper comprising an upper horizontal connecting component, a lower horizontal connecting component and an energy consuming component arranged between the upper horizontal connecting component and the lower horizontal connecting component, wherein both sides of the energy consuming component are respectively provided with at least one buckling restrained component, and optimally, both sides of the energy consuming component are provided with four buckling restrained components. The buckling restrained components are connected with the upper and lower horizontal connecting components through bolts, the buckling restrained components at both sides are connected through bolts, and the energy consuming component is connected with the buckling restrained components through the other bolts or the energy consuming component is connected with the upper and lower horizontal connecting components in a welding manner. The metallic damper adopts the in-plane stress mode, achieves high energy consuming efficiency and stable performance, has higher initial rigidity and avoids the buckling of the energy consuming component by adopting the buckling restrained devices.

Description

technical field [0001] The invention relates to the field of anti-seismic technology of building engineering structures, in particular to a building energy-dissipating metal damper. Background technique [0002] The energy dissipation and shock absorption of building structures refers to the installation of appropriate energy dissipation components in the building structure. The energy dissipation components can be composed of energy dissipation and shock absorption devices and supporting components such as braces, walls, beams or nodes. The metal energy dissipator is an energy-dissipating shock-absorbing device with superior energy-dissipating performance, simple structure, convenient manufacture, low cost and easy replacement. It can be used as an energy-dissipating unit or limiting device in conjunction with a seismic-isolation support or a seismic-isolation system, and it can also be used alone in a building structure as an energy-dissipating device to provide additional...
