摘　　要：为克服传统约束屈曲支撑连接段难控制的缺点,本文构建了双T形内核与方钢管约束屈曲支撑,并对其滞回性能进行了试验研究与有限元分析。分析结果表明:模型受力合理,符合力学原理,支撑能产生良好的耗能效果;设计时建议采用约束比大于3。The connection section of the traditional buckling-restrained brace is hard to control. In order to overcome the fault, this article has constructed double-T-shaped core member and square iron buckling-restrained brace （BRB） by using the same mechanics principle. The article analyzes the hys- teretic behavior of new BRB by using experimental research and finite element analysis. The results prove that the model＇ s behavior which conforms to mechanics principle is reasonable. The new BRB can offer good energy-dissipation capacity. The article gives the advice of these parameter： restraining stiff- ness ratio is greater than 3.
