摘　　要：总结国内外机械、航空等领域关于颗粒阻尼技术的发展现状和取得的成果,讨论并给出了颗粒阻尼技术应用于建筑结构的位置.通过单层和多层钢框架模型的振动台试验,探讨了砂子等材料作为建筑结构颗粒阻尼材料的减震性能和减震效果.结果表明,粗砂作为建筑结构的颗粒阻尼材料,可以提供较大的等效阻尼比,能明显减轻结构的地震反应.The Chinese and international development status and study results of particle damping technology for machinery, aviation and other fields were summarized. The optimal install position in building structures for the application of particle damping technology was studied and given. Sands and other materials were used for particle damping, and the shaking table tests for single and multi-story steel frame model were carried out. The vibration attenuation performance and effect were studied. The results show that the coarse sand, as for particle damping material, can provide a larger equivalent damping, and the seismic responses of structures are reduced significantly.
