Obtaining Critical Buckling Load of a Cantilever Beam by Using Measured Natural Frequencies

Abstract

In this study, buckling critical loads are calculated by using natural frequency values of the first 4 modes obtained by performing experimental modal analysis (EMA) of a uniform cantilever beam. The analytical results are presented with the experimental results comparatively. According to the results it can be said that the vibration data can be used to determine the critical buckling loads of the beams. So there is no need any buckling tests that cause deformation in the test structures or analytical and numerical solutions that need mechanical properties of the beam for obtaining buckling loads.
