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.
