摘　　要：文阐述了耗能减震的概念和原理，提出了耗能减震器设计的新思想，研制开发了多种新型实用耗能（阻尼）减震器，并对其中的圆环耗能器、双环耗能器、加劲圆环耗能器、弹塑性－摩擦复合耗能器等进行了循环荷载试验，考察了耗能器的工作性能和耗能性能。对已装与未装耗能减震器的钢筋混凝土框架模型进行了伪动力对比实验，进一步考察了耗能减震器的减震效果。在试验研究的基础上，对耗能（阻尼）减震结构体系的分析方法进行了研究，并编制了相应的计算软件。试验和分析表明，所研制的耗能减震器工作性能稳定、耗能效率高、减震效果好，构造简单。文章最后对耗能减震技术的前景作了展望。おhis paper gives the concept and mechanism of seismic control by energy dissipation. New energy dissipater design ideas are put forward. On the basis of the idea, some kinds of new energy dissipaters are invented. The comparative experiment of new energy dissipaters with different design parameters under low cyclic reversed loading is conducted and the results show that new energy dissipaters are very effective, the working behavior of which is stable and a great deal of energy is dissipated by friction and yielding of mild steel. The pseudo dynamic testing of two 2story reinforced concrete frame models with and without energy dissipater is conducted and the analysis methods of the structure systems with energy dissipater are presented.
