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, a diamond-shaped H-shaped damper was studied, and the numerical simulation analysis by ABAQUS finite element software verified that the damper has good hysteretic performance. For a 12-story frame structure, the frame-double swinging wall concrete The beam structure and the frame - double limb rocking wall rhombic hole H-shaped steel damper structure dynamic time history analysis, through the analysis of different conditions showed that the diamond-shaped open H-beam damper added to the double swinging wall structure, reaching double Extremity swinging wall structure dampens small earthquakes of dampers, moderate energy consumption and large earthquakes. It also averages the displacement angles between structural layers, reduces the acceleration of structural layers and displaces the apexes of the structure so as to make the structure of double-swinging walls more Good seismic performance.
