摘　　要：采用有限元程序ABAQUS对受压卷边槽钢进行线弹性畸变屈曲分析,在此基础上,对加设隔板和加设连杆两种加固方式的效果进行分析比较。结果表明,在相同的间距布置下,加设隔板对受压卷边槽钢的屈曲荷载提高较大。经过对比,当采用矩形隔板,在1/2半波间距布置隔板时,为最经济有效的布置方式。This paper uses the finite element program ABAQUS to analyze the linear elastic distortional buckling of lipped channel column with two reinforcement measures by adding diaphragms and connecting rods. The results show that lipped channel column with additional diaphragms can enhance more buckling load than that with additional connecting rods. After comparision, we found that adding the rectangular diaphragms to the lipped channel at a distance of a quarter - wave length is the most economical and effective way to strengthen the lipped channel.
