Natural frequencies and buckling stresses of a deep beam-column on twoparameter elastic foundations are analyzed by taking into account the e!ect of shear deformation, depth change (the transverse displacement w can vary in the depth direction of beam-columns) and rotatory inertia. By using the meth

This work presents a method to find the exact vibration frequencies of beams resting on variable one- and two-parameter elastic foundations. The proposed solution is based on a new method that enables one to find the dynamic stiffness matrix for the member including the effects of the variable found

The following comments are motivated by two recent papers concerned with the vibrations and buckling of beams supported on two-parameter elastic foundations. Both papers contain a mistake in the boundary conditions corresponding to a free end in that they use the stiffness matrices for the beam-foun

Exact stiffness and consistent mass matrices for beams on elastic foundations are derived. Using these matrices it is possible to find the natural frequencies and mode shapes of vibrations, for beams fully or partially supported on elastic foundations. Several examples are given for frequencies and

The non-linear vibrations of an elastic beam resting on a non-linear tensionless Winkler foundation subjected to a concentrated load at the centre is presented in this paper. Since the foundation is assumed to be tensionless, the beam may lift off the foundation and there exists different regions na
