The Geometric Failure Mode of Column Buckling

by My Nguyen


Submitted : Fall 2015

The understanding of column buckling is imperative to the design of safe structures and components. Buckling is an instability that leads to a geometric failure in a column or structure. Column buckling occurs when structures such as bridges, railways, and pipes, reach instability due to high compressive stress coupled with slender cross-sectional properties. Neglecting column buckling in design can place the public at risk such as personal injury due to sudden deformation of a column. To determine when the column buckles, we will derive the Euler Buckling theory, which will use the theoretical critical stress to find the measured peak load. To prove the accuracy of this formula, an axial/torsional testing machine will be used to retrieve the peak load of a steel column at the geometric failure point. With the retrieved peak load and the derivation of the Euler Buckling theory, further verifications were made on an Excel spreadsheet to predict additional theoretical peak loads.
