摘　　要：文中探讨了薄壁方钢管-再生混凝土结构中钢管的本构关系和再生混凝土的本构关系,选择一种适合于薄壁方钢管-再生混凝土轴压构件数值分析的本构关系模型,并通过有限元对组合短柱进行模型建立。In this paper,the constitutive relationship of the steel tube in the thin-walled square steel tube-recycled concrete structure and the constitutive relationship of the recycled concrete are discussed,and a constitutive model suitable for the numerical analysis of the thin-walled square steel tube-recycled concrete axial compression member is selected.The finite element model is used to build the composite short column.

关 键 词：组合短柱 本构关系 模型建立
