Abstract

The invention discloses a shear-type stiffened metal damper, which comprises an energy-dissipating steel plate, stiffening ribs are respectively arranged on the left and right sides of the energy-dissipating steel plate, horizontal connecting steel plates are respectively arranged on the upper end and the lower end of the energy-dissipating steel plate, Flange plates are arranged at the front end and rear end respectively, the stiffeners on the left side and the right side of the energy dissipation steel plate are arranged symmetrically or asymmetrically, and the stiffeners on the same side of the energy dissipation steel plate are arranged without crossing. The invention utilizes the advantages of relatively large initial rigidity when the steel plate is stressed in the plane, and prevents the buckling of the energy-dissipating steel plate by means of stiffening, thereby ensuring the energy-dissipating capacity and stability of the damper; There are no cross welds, and the stiffeners can be set in full length without truncating, which is convenient for welding, and the welding quality is easy to guarantee.

Description

technical field [0001] The invention relates to the anti-seismic field of building engineering structures, in particular to a shear type stiffening 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 damping and stiffne...
