摘　　要：分析了预制钢管超高强石渣混凝土叠合柱与钢筋混凝土构件、钢管混凝土构件及非预制钢管混凝土叠合柱相比较的优点.基于实验现象观察的基础上提出计算假设,并以预制钢管超高强石渣混凝土叠合短柱的极限承载力的研究成果为基础,给出了预制钢管超高强石渣混凝土叠合中长柱的承载力计算公式,弥补了《钢管混凝土叠合柱结构技术规程》(CECS188:2005)中未考虑长细比对核心钢管混凝土承载力影响的不足.This paper presented the advantages of composition columns reinforced with the prefabricated SHSCUS filled with steel tubes superior to members made with reinforced concrete, or concrete-filled steel tubular, or those reillforced with the concrete filled with steel tubes by conventional methods, then the hypothesis was put forward based on experimental phenomena observed, and based on the experimental studies on the ultimate bearing capacity of composition columns reinforced with the prefabricated SHSCUS filled with steel tubes subjected to axial load, the formula of its ultimate load capacity was suggested for the columns with medium slenderness ratio, on which the effect of slenderness ratio on the ultimate load capacity of core concrete-filled steel tube is considered.
