The study, Finite element investigation of stress, deformation and displacement of I section and C section steel columns was successfully carried out. Researchers created a model of I section column with 5mm×10mm for both top and bottom flanges and 5mm × 30mm for central member. Similarly, C section column model was also created with 5mm×10mm for the two end attachments and 5mm×10mm for main member. Both columns retained a vertical height of 40mm, with assigned material being Steel Alloy. Each of the columns was subjected to top compressive load of 20 kN, with the base to fixed constraints and simulation was run using finite element analysis software. Von Mises stress was found to be 14581MPa for I section column and 16030MPa for C section column. Since, yield strength of the assigned material is 250 MPa, it suggested that failure of column due to yielding is possible under the given conditions and would be more predominant when C section column is used. Also, the 3rd principal stress for the I section column was 15MPa and 311MPa for C section column. These results indicated that induced stress due to compressive loading is higher in C section column. In addition, maximum stresses induced in columns were found to be 5115MPa for I section and 4346MPa for C section. Since, the maximum compressive stress of structural steel material is 320MN/m2, therefore I section column would experience failure faster compare to C section column under the given conditions. Furthermore, Maximum deformations/strains induced in columns were found to be 0.03244 for I section and 0.02756 for C section. Therefore I section column would experience failure faster compare to C section column under the given conditions. Maximum displacements were observed to be 1.018mm for I section column and 0.2211mm for C section column. These results suggested that the I section column showed lower stability with lower safety factor of 15ul. C section column showed higher stability with safety factor of 16.38927ul.
