Description

Technical Field

[0001] The utility model relates to the technical field of anti-seismic dampers, in particular to a multi-dimensional stiffened high-ductility metal shear type anti-seismic damper. Background Art

[0002] Metal shear dampers are seismic devices used in building structures. They typically consist of multiple layers of metal plates that shear to dissipate seismic energy, thereby reducing the vibration amplitude and damage to the structure during an earthquake. This type of damper can effectively improve a building's seismic resistance, protecting it and its interior from the effects of earthquakes.

The stiffening plates described in this patent are only disposed transversely and longitudinally, resulting in limited effectiveness and impractical use. Therefore, we have introduced a multi-dimensionally reinforced, high-ductility metal shear-type seismic damper. Utility Model Content
