A buckling analysis, bearing out the prominent differences in buckling loads of a pin-ended rod embedded in a Winkler and Wieghardt-type foundation, is given by T. E. Smith. Herein it is shown that existing results in the case of beams resting on a Winkler-type foundation and subjected to simultaneous action of axial loads, compressive or tensile and transverse loading, can be utilized after suitable modification to represent the same structure resting on a Wieghardt-type foundation. Modified results in one case are shown.
