Background

Under the action of earthquake, the conventional building structure is inevitably damaged, the introduction of the energy dissipation component can effectively dissipate earthquake energy, so that the deformation of the structure is mainly concentrated in the energy dissipation component, and the damage effect of the earthquake on the building structure is reduced or even avoided. The shear type metal damper is used as a passive control device in the fields of energy dissipation, earthquake resistance, disaster prevention and reduction of structures, has simple structure and low cost, and is widely applied to the field of earthquake resistance.

Currently, the metal shear dampers of the prior art are considered to provide load bearing, stiffness and energy dissipating capabilities only in the directional plane of one of the main axes of the building structure. However, the actual seismic action often does not occur along the main axis direction of the structure, and the structure can present the deformation characteristic of bidirectional coupling under the seismic action; the existing metal shear damper mostly consumes energy in a single direction in a plane, is difficult to adapt to bidirectional coupling deformation, and cannot provide stable and reliable bearing capacity, rigidity and energy consumption capacity under the bidirectional coupling deformation.
