摘要
现行国家规范《冷弯薄壁型钢结构技术规范》(GB50018-2002)提出适用于各种型钢构件板组的约束系数统一计算公式。针对冷弯薄壁卷边槽钢纯弯构件畸变屈曲运用直接强度法计算受压翼缘板组约束系数,并与GB 50018-2002计算结果比较,得到一些有价值的结论,供设计研究参考。
Uniform constraint coefficient formulas used for various sections with different plate elements are given in the Current national specification ＂Technical Code for Cold-Formed Thin-Walled Steel Structure＂ （GBS0018-2002）,For the pressed flanges of cold-formed lipped channel flexural members, the coefficients of constraint action between plate components in distortional buckling mode are calculated by Direct Strength Method（DSM）：The results calculated by DSM and GBS0018-2002 are compared. Some valuable conclusions are drawn and can give reference to the research and design.
