摘　　要：为了解决钢管混凝土异形柱及相关梁柱节点构造创新不足的问题,以异形柱的发展改进历程为研究背景,指出钢管混凝土异形柱的优势所在.依据增强外钢管对内部混凝土的约束作用和增加柱肢单元内各钢板稳定性2种思想,将钢管混凝土异形柱分为带约束拉杆或加劲肋的钢管混凝土异形柱、多腔式钢管混凝土异形柱、缀材连接的钢管混凝土异形柱4种类型,对异形柱本身构造改进方面的研究进行综述;按传力构件与柱肢钢管的相对位置,将钢管混凝土异形柱的梁柱节点分为传力构件在钢管内部式和传力构件在钢管外部式2种类型,对相关梁柱节点构造创新方面的研究进行综述.同时,剖析了以上两方面研究现状的不足,指出今后钢管混凝土异型柱及其梁柱节点需要进一步深入研究的关键问题.To solve the problems of insufficient structural innovation of concrete-filled steel tubular(CFST)special-shaped columns and corresponding beam-column joints,the process of development and improvement of the special-shaped column was taken as the research background,and the advantages CFST special-shaped column were pointed out.According to the two ideas of strengthening the restraint effect that the external steel tube applied to internal concrete,and increasing the stability of steel plates inside column limb unit,the CFST special-shaped columns were divided into 4 types with binding bars or stiffener ribs,multi-cell,and lacing members,and then the structural improvements of the 3 types of special-shaped columns were summarized.According to the relative position between the force transfer member and the steel tube of the column limb,the joints between the CFST special-shaped columns and beams were divided into 2 types with the force transfer member in the steel tube,and the force transfer component outside the steel tube.Moreover,the deficiencies of the CFST special-shaped column and the corresponding beam-column joint were analyzed,and that the key problems need to be further investigated was addressed.
