【摘要】 介绍了自复位剪力墙复位性能的基本概念,定义自复位能力系数,用于剪力墙的自复位能力大小。利用ABAQUS有限元分析软件,建立自复位剪力墙模型,对模型进行低周反复加载,分析结构的残余变形,最大位移、墙体角部破坏情况、复位能力、耗能能力等,并系统分析软钢阻尼器数量、长度、位置对自复位剪力自复位性能的影响,建立自复位能力系数、墙体受压损伤指标与阻尼器相关参数的关系曲线。更多还原

【Abstract】 With the introduction of basic concepts about self-centering shear walls,this paper defines the coefficient of self-centering ability of shear wall.By using the finite element analysis software ABAQUS,a selfcentering shear wall model was constructed.Structural analyses were performed to study the residual deformation,the maximal displacement,wall corner damage,self-centering capacity,energy dissipation capacity.Systematic analyses show how the number,length and position of mild steel dampers affect the self-centering wall performances.更多还原
