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 ...

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.

A beam resting on a tensionless Winkler foundation

Computers & Structures, 1995
Abstract A general method for the analysis of the deflection of an elastic straight beam resting on a tensionless Winkler foundation is presented. Using Newton's method and the Finite Element Method, a numerical method has been developed that finds the solution and has a quadratical rate of convergence.

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 ...

The improved foundation modulus for the use of Winkler foundation

2010 International Conference on Mechanic Automation and Control Engineering, 2010
An improved calculating method for the foundation modulus of Winkler foundation is presented in this paper. The calculating results of foundation modulus respectively from Biot's and Vesic's model are different greatly through the analysis to the two methods.

DBEM Analysis of Beams on Modified Elastoplastic Winkler Foundation

1991
The problem of a beam on an elastoplastic Winkler medium is handled using a general Direct Boundary Element Method approach. The case of concentrated internal loading is considered, and the governing equations are obtained both following the classic beam subdivision approach and considering the beam loaded by a family of Dirac delta distributions and ...

Viscoelastic Winkler Foundation with Shear Interactions

Journal of the Engineering Mechanics Division, 1961
Concept of Pasternak-foundation, consisting of Winkler-foundation with shear interactions, is extended to case of viscoelastic behavior; formulation for vertical surface displacements due to creep and solutions for several loading cases are worked out; procedure to determine viscosity parameter and visco-compressibility parameter of vertical foundation
