摘　　要：本文提出了一种新型的基于滑移连接的分阶屈服型金属阻尼器,布设在连梁跨中构成消能连梁。主要介绍了其构造形式、耗能机理及设计方法。并利用有限元软件ABAQUS模拟,分析了其在低周往复加载下的滞回性能。结果表明:该阻尼器滞回曲线饱满,耗能性能优良,能够实现第二阶段的刚度增强,具有良好的减震效果。该阻尼器构造简单,制作方便,采用高强螺栓连接,更换方便,有广阔的工程应用前景。A new type of stage yield metal damper is proposed based on slip connection,which is arranged with coupling beams in the middle of the span to form energy-dissipating coupling beam.The structure,energy consumption mechanism and design method are briefly described.The finite element software ABAQUS is used to simulate and analyze its hysteretic performance under low-cycle reciprocating loading.The results show that the damper has full hysteretic curve,excellent energy dissipation performance,can enhance the stiffness in the second stage,and has good damping effect.The damper has the advantages of simple structure,convenient manufacture,high-strength bolt connection and convenient replacement.It has broad engineering application prospects.
