摘　　要：采用ANSYS软件建立方钢管再生混凝土轴心受压短柱有限元分析模型,考查骨料取代率对钢管再生混凝土柱荷载-应变曲线和局部屈曲性能的影响。结果表明,钢管再生混凝土柱轴压承载力随着骨料取代率的增加而降低,骨料取代率变化对钢管再生混凝土柱的延性和局部屈曲性能影响不大。The finite dement model of recycled concrete -filled square steel tubular stub column under axial pressure was established by using ANSYS, this paper investigates the effect of recycled aggregate replacement percentage on the load - deformation relationship curves of the columns and local buckling per-formance. It is found that the axial compressive capacity decreases with the increase of recycled aggregate replacement percentage, and the variation of recycled aggregate replacement ratio does not affect the ductility and local buckling performance.
