This study was conducted to investigate the load-bearing capacity of a single angle column under various loading conditions to determine the loading condition offering the highest load- bearing capacity. In all cases, the load is transferred through one leg (or two legs) of the angle which has a smaller cross-sectional area compared to the total area of the angle profile. The main objective of this study is to develop almost all of the possible support conditions for the single angle section and carry out laboratory tests on the chosen specimens to determine the most suitable one. Also, there are some finite element investigations done using ABAQUS software to find out the maximum forces in which all the elements of the structures remain their linear behavior and the stress spots concentration. Based on the obtained results, it is possible to increase the axial critical load of a single angle by using the connections at the main axis of the section.
