A research work was undertaken at The Department of Civil Engineering of University of Asia Pacific (UAP), Dhaka, Bangladesh during April to November 2015. Biaxial bending means the column is carrying bending by one or both axis with axial load and with calculations it is possible to put those unique values into a pattern to make an interaction diagram with balanced failure zone, tension failure zone and finally compression failure zone of a short or slender column. By using programming it is possible to make the calculations in seconds. The method is to make functions and calling them to solve certain specific values to generate the diagram pattern. The outcome was diagram data generating application having the ability to combine programming and “Civil Logic”. This is made for students and Civil Engineers who want to make interaction diagrams for designing a short, square and even slender columns with ease.
