摘　　要：采用有限条软件CUFSM和有限元软件ABAQUS分别对Q355钢冷弯薄壁卷边槽钢梁进行弹性屈曲应力比值与极限承载力研究,极限承载力随畸变屈曲应力与局部屈曲应力比值fcrd/fcrl的增加而减小,二者呈反比例关系。The elastic buckling stress ratio and ultimate bearing capacity of Q355 steel cold-formed thin-walled lipped channel beam were studied by CUFSM finite strip software and ABAQUS finite element software.The results show that the ultimate bearing capacity decreases with the increase of the ratio of the distortional buckling stress to the local buckling stress f crd/f crl,with an inversely proportional correlation between them.

关 键 词：畸变与局部相关屈曲 极限承载力 弹性屈曲应力比值
