Abstract
The cold formed profiles developed through the conformation of thin plates of steel, has been an attractive constructive solution for several aspects such as economy and speed to execute some works. Furthermore, its high slenderness allows to build lighters and more efficient structures. So, the buckling coefficient has great importance to design a profile because it is possible to calculate the critical buckling stresses. Thus, the objective of this work is to obtain the curve of the buckling coefficients of the cold formed profile S with a sloped web with compression stress causing local buckling. This profile can be used in industry to build light steel frame structures and do not have specific studies of buckling coefficients. The numerical analysis software Abaqus™ and CUFSM were used to obtain the critical buckling loads. The results obtained were used to adjust a curve of the buckling coefficient versus the geometry ratios and will contribute to future structural stability calculations.
