Beams on Variable Winkler Elastic Foundation

Journal of Applied Mechanics, 1986
A stiffness approach is presented for computing the solution of beams on variable Winkler foundation. The solution may be achieved using only a small number of elements along the beam. Accuracy is dependent only on a preset user criterion. A numerical example demonstrates the efficiency and accuracy of the procedure.

Beams on quasi-Winkler foundations

Engineering Structures, 1982
Abstract When an elastic foundation is incapable of exerting tensile reactions on the beam it supports, the Winkler model cannot be used throughout the whole span of the girder. The resulting problem leads to a set of nonlinear equations, and its complexity is further increased due to the necessity of visualizing the deflected shape a priori if the ...

Beam-Plate System on Winkler Foundation

Journal of the Engineering Mechanics Division, 1977
A superposition principle is employed to study the infinite plate reinforced by a centrally loaded finite beam where both rest on a Winkler foundation. The problem is intended to relate to a floating arctic ice ridge embedded in an ice sheet. The ridge is loaded vertically by a vessel breaking ice in a bending mode. After formulating the beam and plate

Beams on nonlinear winkler foundation with gaps

Computers and Geotechnics, 1988
Abstract The analysis of beams on a Winkler foundation is very common in engineering. In many practical problems nonlinear foundation behavior should be considered. In some cases a gap may exist between the beam and the nonlinear foundation. Based on an exact solution for a finite beam on linear elastic foundation, an iterative procedure for a ...

Analysis of beams on nonlinear winkler foundation

Computers & Structures, 1989
Abstract The analysis of beams on Winkler foundations is very common in engineering. In many practical problems nonlinear foundation behavior should be considered. Based on an exact solution for a finite beam on a linear elastic foundation an iterative procedure for a piecewise linear foundation is formulated.
