Study on seismic performance of a new type of metal damper with opening coupling beam

提出了一种不同开孔形式的连梁金属阻尼器。基于ABAQUS软件对其在低周往复荷载作用下的力学性能进行了研究,分析了不同开孔形式对该连梁阻尼器抗震性能的影响,并给出了最佳开孔建议,指出该阻尼器能够提高传统墙肢结构的抗震性能,对剪力墙结构的抗震设计具有重要应用价值。

In this paper,a metal damper with different opening forms is proposed.Based on ABAQUS software,the mechanical performance of the coupling beam damper under low cycle reciprocating load is analysed,the influence of different opening forms on the seismic performance of the coupling beam damper is analysed,and the best opening suggestions are given.The damper can improve the seismic performance of traditional wall limb structure,which has important application value for the seismic design of shear wall structure.
