BUCKLING OF CONTINUOUSLY SUPPORTED BEAMS

The buckling of infinite beams continuously supported by a semi-infinite elastic continuum is investigated. The buckling loads were determined when the beam rests on a two-dimensional elastic continuum and also when the foundation extends beyond the width of the beam. The effect of the outside foundation is shown by comparing the obtained buckling loads. The author considered the use of the Winkler foundation, in his buckling analysis, but because of its periodicity, chose to use the Fourier series and transforms for the transverse direction. The effect of extending the elastic continuum beyond the width of the beam is shown by a graphical comparison.
