摘　　要：本文对菱形开孔H型钢阻尼器进行研究,通过ABAQUS有限元软件进行数值模拟分析,验证了此种阻尼器具有良好的滞回性能;对某12层框架结构、框架-双肢摇摆墙混凝土连梁结构和框架-双肢摇摆墙菱形开孔H型钢阻尼器结构进行动力时程分析,通过不同工况的分析结果表明,菱形开孔H型钢阻尼器加入双肢摇摆墙结构中,达到了双肢摇摆墙结构对阻尼器小震屈服、中震耗能、大震更换的要求;平均了结构层间位移角,减小了结构层间加速度、结构顶点位移,使双肢摇摆墙结构具有更加良好的抗震性能。In this paper,the diamond hole H-beam damper is studied. Through numerical simulation analysis with ABAQUS finite element software,the well-performed hysteretic properties of the damper are verified. Dynamic time history analysis is perpectively used on a 12 layer frame structure,rocking coupled wall with concrete beam structure and rocking coupled wall with diamond hole H-steel structure. The results of different working conditions show that the diamond hole H-beam damper in rocking coupled wall structure achieves the requirement of rocking coupled wall structure ＇s damper： frequent earthquake yield,basic earthquake dissipation,strong earthquake change; the diamond hole H-beam damper averages interlayer displacement angle,reduces the structure interlayer acceleration,top displacement of structure,and make rocking coupled wall structure to have better seismic performance.
