Abstract
This paper examines the anti-buckling graded yield type metal damper, which is formed by combining two medium-damping dampers that use dampers with different yield properties to dissipate energy and have multi-level yield functions. This design can effectively prevent excessive yield or failure of a single damper during large earthquakes, thereby improving the reliability and safety of the damper. The paper investigates the energy dissipation of the anti-buckling graded yield type metal damper through experiments and numerical simulations, and analyzes its parameters. The conclusion is that the damper exhibits good energy dissipation characteristics and stability, and can maintain a large hysteresis loop area under larger loading displacements, indicating higher energy dissipation efficiency. Additionally, the damper has high environmental adaptability and can adjust the material and size of the shear and bending energy-absorbing plates to meet different seismic resistance requirements, ensuring the damper's initial stiffness changes and energy dissipation capabilities under different requirements.
