Buckling of a simply-supported beam between two unattached elastic foundations.

Discussion of “Buckling of Beams Supported by Pasternak Foundation”

“…8 and 9 show two These comments suggest that a realistic model for rigid pavements is more complex than 'that used by the author and that his results may not be directly applicable to rigid pavements. As a minimum, the fact that soil foundations can support little or no tensile force should be incorporated into the foundation model (25,32), and the pavement should be modeled as being only partially supported (26,27 ,28,29,33). The literature (24,30) indicates that buckling (or tenting) occurs as compressive axial stresses force the pavement upward separating it from the soil foundation.…”
