The elastic foundation beam theory has been widely used in civil engineering, including railway, tunnel, and building foundations. With the development of fabricated structures, more beams need to be prestressed. In order explore frame with anchor-cable slope reinforcement project, this article, prestress is applied both ends beam. Then, according calculation method internal force deformation u...

In this study, the buckling and free vibration of Timoshenko beams resting on variable elastic foundation analyzed by means of a new finite element formulation. The Winkler model has been applied for elastic foundation. A two-node element with four degrees of freedom is suggested for finite element formulation. Displacement and rotational fields are approximated by cubic and quadratic polynomia...

For dynamic analyses of railway track structures, the algorithm of solution is very important. For estimating the important problems in the railway tracks such as the effects of rail joints, rail supports, rail modeling in the nearness of bridge and other problems, the models of the axially beam model on the elastic foundation can be utilized. For studying the effects of axially beam on the ela...

Beams supported by elastic foundations are one of the complex soil-structure interaction problems that have been studied using "beam on foundation" concept. To support loads, structural foundation and soil continuum must work together. The development more accurate model simpler procedure critical for safety cost-effective construction such type structure. Three nodded beams based Timoshenko be...

Free vibration analysis is carried out on axially inhomogeneous beams resting Winkler-Pasternak elastic foundation. The material properties of the beam like Young’s modulus, modulus rigidity and density are considered to be varying along length direction following constant, linear exponential models. subjected different combinations clamped simply supported boundary conditions. formulation base...
