摘　　要：为了研究新型结构构件钢板笼混凝土短柱的轴心受压承载力,在已有受约束混凝土本构关系基础上,根据箍筋约束混凝土的拱作用原理,对钢板笼套箍约束混凝土承载力进行分析,推导出钢板笼混凝土轴压短柱的承载力公式,并将计算结果与试验数据进行对比.研究结果表明:钢板笼对混凝土的横向约束与钢管混凝土相似,纵向连接成角钢约束力强,模型计算结果和试验数据吻合较好.Based on the existed concrete constitutive relationship and arch action principle of stirrups confined concrete.The prefabricated cage system ferrule form and spacing constraints concrete bearing capacity are investigated.The formula of prefabricated cage system bearing capacity of axially loaded concrete is proposed,and the calculation results are compared with experimental data.The result shows that the lateral confinement of prefabricated cage system for reinforcing concrete is similar to concrete-filled steel tube,the confinement of angle steel connected longitudinally is strong,and the calculation results agree well to experimental data.
