摘要
基于直接强度法,拟合冷弯薄壁卷边槽钢轴压柱局部屈曲、畸变屈曲实用计算公式,取局部屈曲、畸变屈曲与整体屈曲三者的最小值作为轴压柱屈曲计算结果。3种屈曲计算值与有关试验值的对比分析表明,所提出的实用计算公式在适用范围内与试验值吻合较好,且计算公式简单、实用,避免了对专用计算程序的依赖。
Based on the Direct Strength Method（DSM）,the applied calculation formulas fitting for the local and distortional bucklings of cold-formed lipped channel columns under axial pressure is carried out.The minima of local,distortional and global bucklings are the buckling carrying capacity calculation results.A comparative study is made between the calculation results and experimental ones.It shows that in applicable scope the results of applied calculation formulas agree well with those of the experiments.The applied calculation formulas are simple,practical and independent of the dedicated computer program.
