针对框架—核心筒体结构体系的特点和低碳钢的优良性能，在吸取国内外学者有关研究成果的基础上，开发研制了一种新型的耗能减震器—环形低碳钢滞后阻尼器。这种减震器的优点是耗能区域明确，可安装在外框架和筒体结构之间的施工缝中。试验结果表明，该环形减震器性能稳定，耗能效果较好，且变形主要集中在预设的工作区域内，基本达到了原设计要求。最后，提出了环形减震器的恢复力计算模型。
Aiming at the characteristics of frame-core tube structural system and the excellent performance of mild steel, a new type of energy-absorbing shock absorber, annular low carbon steel hysteresis damper, was developed based on the research results of domestic and foreign scholars. . The advantage of this shock absorber is that the energy dissipating area is clear and can be installed in the construction joint between the outer frame and the cylinder structure. The experimental results show that the ring damper has stable performance and good energy dissipation effect, and the deformation is mainly concentrated in the preset working area, basically meeting the original design requirements. Finally, the restoring force calculation model of ring damper is proposed.
