摘　　要：提出钢骨混凝土异形柱的概念,通过4根不对称T形截面钢骨混凝土异形柱正截面承载力的试验研究,揭示了钢骨混凝土异形柱的工作机理、破坏形态和极限承载力,验证了平均应变的平截面假定.编写钢骨混凝土异形柱正截面承载力计算的计算机程序.试验和程序计算结果表明,钢骨混凝土异形柱与钢筋混凝土异形柱相比,承载力明显提高.The concept of SRC special-shaped columns was presented first. Based on the experimental study of 4 SRC special-shaped column with asymmetrical T-shaped cross-section, this paper reveals the action behavior, failure patterns and bearing capacity of SRC special-shaped columns, examines the hypothesis of plan cross-section of average strain. By means of finite element numerical analysis , a set of computer programs about the bearing capacity of normal section of SRC special shaped columns were compiled. The bearing capacity of SRC special-shaped columns and reinforced concrete （RC） special-shaped columns were compared, the results show that the bearing capacity of SRC columns improve much than that of RC columns.
