The lightweight design and miniaturization of metallic dampers have broad application prospects in seismic engineering. In this study, the superplastic property and the maximum energy dissipation capacity per unit mass of low-yield-strength steel (LYS) are investigated via comparison with those of several common metallic damping materials by tests. Additionally, the boundary constraints of an LYS shear panel damper are studied further. Our experimental results suggest that LYS is an excellent damping material for achieving the lightweight design goal. A novel design of a lightweight damper, having excellent deformation ability and robust mechanical properties, is presented. The findings of this study are expected to be useful in understanding the lightweight design of dampers.
金属阻尼器的轻量化设计与小型化在地震工程中具有广阔的应用前景。在本研究中，通过试验将低屈服强度钢（LYS）与几种常见金属阻尼材料的超塑性性能和单位质量的最大耗能能力进行比较，对低屈服强度钢展开研究。此外，还进一步研究了低屈服强度钢剪切板阻尼器的边界约束。我们的实验结果表明，低屈服强度钢是实现轻量化设计目标的优良阻尼材料。提出了一种具有优异变形能力和稳健力学性能的新型轻量化阻尼器设计。预期本研究结果将有助于理解阻尼器的轻量化设计。
