摘　　要：应用GB 50017-2003《钢结构设计规范》中格构柱板条模型和缀条模型相叠加的方法,对开孔钢板连接L形方钢管混凝土组合异形柱换算长细比计算方法进行了推导。建立了与试验结果相吻合的有限元模型,并以长细比为变量,验证了换算长细比计算公式的正确性。With the method of mutually superimposition of the lacing bar model and the batten bar model both from Code for Design of Steel Structures （GB 50017--2003）,equations of slenderness ratio for L-shaped column composed of concrete-filled square steel tubes connected by perforated steel plate were deduced. Finite element model was established, which was consistent with the experimental results. Using this finite element model, with the slenderness ratio being a variable, the correctness of the equations of slenderness ratio for L-shaped column composed of concrete-filled square steel tubes connected by perforated steel plate was verified.
