【摘要】文章采用 ABAQUS 有限元软件建立了 5 根再生混凝土柱数值模型，进行轴压作用下不同设计变量对再生混凝土柱
受力性能的研究。轴压作用下再生混凝土柱的破坏形式与普通混凝土柱类似；随着再生骨料取代率和长细比的提高，柱的
轴心受压承载力降低；随着再生骨料取代率的增加，柱的侧向挠度减小。文章建立的ABAQUS 有限元模型可以进行类似轴

【Abstract】In this paper, ABAQUS finite element software is used to establish five numerical models of recycled concrete columns,
and the mechanical properties of recycled concrete columns under axial compression are studied with different design variables. The
results show that the failure mode of the recycled concrete columns under axial compression is similar to that of the ordinary
concrete columns; With the increase of replacement ratio and slenderness ratio of recycled aggregate, the axia
