摘　　要：方钢管混凝土组合异形柱是一种新型的异形柱结构形式,十字形截面组合异形柱是其主要柱形之一。推导出采用斜缀条连接的十字形截面组合异形柱的等效长细比简化计算公式,研究了采用叠加理论计算十字形截面方钢管混凝土组合异形柱的可行性,并结合通用有限元程序ANSYS进行验证。Column with section of concrete-filled square tubes is a new type of special-shaped column and crisscross combined column of concrete-filled square tubes is a representative one. The simplified equation of slenderness ratio is deduced for crisscross combined column of square steel tubes which are connected by the diagonal lacing bar. The feasibility of superposition theory for crisscross combined column of concrete-filled square tubes is studied, and it is verified by the analysis with ANSYS.
