摘　　要：提出一种由金属圆管结合H型钢组成的阻尼器,建立了阻尼器的有限元模型,在循环荷载作用下采用非线性静力分析方法进行分析。通过有限元方法进行了参数研究,包括研究金属圆管的厚度、长度和直径对金属圆管阻尼器抗震性能的影响。结果表明:随着圆管径厚比的增加,阻尼器的刚度、屈服承载力和耗能会增大;圆管长度的增加,阻尼器的刚度和承载力有所提升,对耗能没有影响。A damper composed of metal round tube combined with H-beam was proposed,and a finite elementmodel of the damper was established,which was analyzed by nonlinear static analysis method under cyclic load.Thefinite element method was used to study the parameters,including the influence of the thickness,length and diam-eter of the metal round tube on the seismic performance of the metal round tube damper.The results show thatwith the increase of the diameter-thickness ratio of the round tube,the stiffness,yield bearing capacity and energydissipation capacity of the damper will increase.The increase in the length of the round tube increases the stiffness and bearing capacity of the damper,which has no effect on the energy dissipation capacity.
