摘　　要：首先结合钢管混凝土柱、钢筋混凝土异形柱的优点和不足,介绍了异形钢管混凝土的特点和研究背景。从异形钢管混凝土柱的截面构成形式、静力性能和抗震性能介绍了国内当前异形钢管混凝土柱的试验研究与理论分析的部分研究工作;简要探讨了异形钢管混凝土柱的研究方法;并将已有异形钢管混凝土轴压承载力试验值与现有钢管混凝土不同规范的计算值进行了比较。结合已有的研究现状,提出了异形钢管混凝土柱尚有待进一步研究的若干关键力学问题,最后展望了异形钢管混凝土结构在工程中的应用前景。Characteristics and research background of concrete-filled specially shaped steel tube structure were introduced. Advantages and shortcomings of concrete filled steel tube structure and concrete structure with specially shaped columns were described. Section-constitution, static and dynamic behavior studies of concrete-filled specially shaped steel tube columns in China were reviewed. The methods used for studying concrete-filled specially shaped steel strength were discussed briefly. The existing experimental results of con- crete-filled specially shaped steel tube stubs were compared with the predictions of different codes. Some key problems on structural behaviors of concrete-filled specially shaped steel tubes were summarized. The future of concrete-filled specially shaped steel tube structure in engineering was prospected.
