摘　　要：在分析比较GB 50018-2002冷弯薄壁型钢结构技术规范和GB 51022-2015门式刚架轻型房屋钢结构技术规范的基础上,对卷边槽钢梁极限受弯承载力计算方法进行了探讨和比对分析。计算结果表明:按GB 50018-2002冷弯薄壁型钢结构技术规范计算冷弯薄壁卷边槽钢梁是可行的,经试验验证,偏于安全。Based on the contrast analysis of Technical Code of Cold-formed Thin-wall Steel Structure(GB 50018-2002) and Technical Code for steel Structure of Light-weight Building with Gabled Frames(GB 51022-2015),analysis and discussion are mentioned about the ultimate load-carrying capacities of cold-formed thin-wall steel lipped channel beams. The results showed that,it is relative safety in calculation the simply supported lipped channel beams according to Technical Code of Cold-formed Thin-wall Steel Structure(GB 50018-2002).
