Application of cold-formed steel is increased in civil engineering sectors, including railway carriages, bridges and trusses. This work focusses on the angle column under axial load. Geometric and material nonlinearity were added into the FE model, which improved accuracy and reliability. The FE model was checked using test data from research articles. The results revealed good agreement between the experimental data and FE model. In addition, parametric research was conducted to investigate the effect of two essential parameters: intermediate stiffeners and effective length, on the axial strength of CFS equal angles. The study attempted to determine the impact of these characteristics on the axial strength of the sections by altering them throughout a range of values. The collected data were analysed, and a design curve was created based on the findings.
