Abstract

The invention discloses a metal damper provided with restraining devices and stiffening ribs. The metal damper comprises an energy consumption steel plate, horizontal connecting steel plates arranged above and below the energy consumption steel plate, wing edge plates arranged at two ends of the energy consumption steel plate as well as the stiffening ribs and the restraining devices which are arranged on two sides of the energy consumption steel plate, wherein the energy consumption steel plate is welded with the upper and low horizontal connecting steel plates; the energy consumption steel plate is welded with the wing edge plates at two ends of the energy consumption steel plate; the restraining devices are respectively arranged on two sides of the energy consumption steel plate; bolt holes are formed in the restraining devices; and the restraining devices on two sides of the energy consumption steel plate are fixedly connected by bolts. According to the metal damper disclosed by the invention, the energy consumption capability and the stability of the damper are ensured; no cross weld joints exist between the stiffening ribs on the same side of the energy consumption steel plate; the stiffening ribs can be arranged in a through way without being cut off and is convenient to weld; the welding quality is easy to ensure; and the restraining devices are independent from the energy consumption steel plate, so that the damage to the energy consumption steel plate as the welding of the stiffening ribs on the energy consumption steel plate is avoided.

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 provided with restraint devices and stiffeners. 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 ...
