摘　　要：为研究冷弯薄壁卷边槽钢纯弯构件截面分类,基于试验数据验证后的有限元模型,对不同板件宽厚比下冷弯薄壁卷边槽钢纯弯构件进行了大量的参数分析。结果表明:抗弯承载力随翼缘与腹板宽厚比的减小而增大。在考虑翼缘与腹板相关作用的前提下,基于截面承载力得出板件截面宽厚比限值,提出了冷弯薄壁卷边槽钢纯弯构件截面分类方法。In order to study the section classification of cold-formed thin-walled lipped channel steel pure bending members,a large number of parameter analyses of cold-formed thin-walled lipped channel steel pure bending members with different width-to-thickness ratios of plates were carried out by using the verified finite element model.The results show that the flexural capacity is inversely proportional to the width-to-thickness ratio of flange and web.On the premise of considering the correlation between flange and web,the width-to-thickness ratio limit of plate section was obtained based on the bearing capacity of section,and the section classification method of cold-formed thin-walled lipped channel steel pure bending members is proposed.
