Problems solved by technology

However, the actual earthquake action often does not occur along the main axis of the structure, and the structure will show two-way coupling deformation characteristics under the earthquake action; most of the existing metal shear dampers consume energy in one direction in the plane, and it is difficult to adapt to two-way coupling deformation , unable to provide stable and reliable bearing capacity, stiffness and energy dissipation capacity under two-way coupling deformation

Abstract

The invention discloses a bidirectional shearing metal damper. The bidirectional shearing metal damper comprises two end plates which are oppositely arranged up and down, wherein a transverse energy consumption plate and a longitudinal energy consumption plate which are perpendicular to each other are connected between the two end plates, one side of the longitudinal energy consumption plate is in contact with the side wall of the transverse energy consumption plate, the upper ends and the lower ends of the transverse energy consumption plate and the longitudinal energy consumption plate are rotationally connected with the corresponding end plates, the transverse energy consumption plate can rotate back and forth in the direction of the longitudinal energy consumption plate, and the longitudinal energy consumption plate can rotate back and forth in the direction of the transverse energy consumption plate. According to the bidirectional shearing metal damper, bidirectional separate energy consumption can be realized, bidirectional coupling deformation can be effectively adapted, and stable and reliable bearing capacity, rigidity and energy consumption capacity can be provided under the bidirectional coupling deformation.

Description

technical field [0001] The invention relates to the technical field of earthquake resistance and disaster prevention of building structures, in particular to a bidirectional shear metal damper. Background technique [0002] Under the action of earthquakes, conventional building structures are inevitably damaged. The introduction of energy-dissipating components can effectively dissipate the seismic energy, so that the deformation of the structure is mainly concentrated in the energy-dissipating components, thereby reducing or even avoiding the damage caused by the earthquake to the building structure. destructive effect. Shear-type metal damper, as a passive control device in the field of structural energy dissipation, anti-seismic and disaster prevention and mitigation, has a simple structure and low cost, so it has been widely used in the field of anti-seismic. [0003] At present, the metal shear dampers in the prior art only consider their ability to provide bearing cap...
