In this study, different forces were applied to angled drilled I columns. The stress analysis and stress concentration effects occured in the material under these forces have been determined. Results of Ansys were compared with the results obtained by mathematical calculation. As a result of the comparison of mathematical calculations with the results of analysis performed through Ansys elongation in the column that is drilled at an angle of 90 degrees is less while in drill column with 15, 30, 45, 60, 75 degrees was found to be greater elongation. In addition, the stress concentration effect occurring in an angled hole was calculated.
