高强薄壁冷弯卷边槽钢柱承载力计算方法
Calculation method for load-carrying capacity of high strength thin-wall cold-formed lipped channel columns under axial compression
【摘要】 在分析比较有效宽度法(EWM)和直接强度法(DSM)的基础上,以1 mm厚Q345冷弯薄壁卷边槽钢柱为例,对其极限承载力进行了较深入的探讨和对比分析,计算与试验结果表明:按GB 50018-2002冷弯薄壁型钢结构技术规范计算槽钢柱是可行的。
【Abstract】 Based on the contrast analysis of the Effective Width Method and the Direct Strength Method,analysis and discussion are mentioned about the ultimate load-carrying capacities of 1 mm thickness Q345 cold-formed thin-wall steel lipped channel columns. The calculation and test results showed that,it is relative safety in calculation the lipped channel columns according to GB 50018-2002 Technical Code of Cold-Formed Thin-wall Steel Structure.
