In this paper, the double lipped channel cold-formed steel column is analyzed by finite element method. Compared with the code both at home and abroad, convenient and practical design formulas have been figured out. The finite element model in this paper was compared with existing data analysis, and the results show that the model precision can meet the needs of the analysis. Through finite element analysis of double lipped channel cold-formed steel column, we can get the influence of a relative size, the plate width, on the bearing capacity of the local stability. The specification about plate buckling under the influence of the common effect of the different types of adjacent panel has no clear rules. Under even pressure, we get the general calculation formula under certain conditions. The conclusion can be used for reference in the standard revision.
