Calculation method for internal force and deformation of the prestressed I-beam on the elastic foundation

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 under concentrated equivalent load prestressed structure, three new methods: finite difference (FDM) Euler–Bernoulli on Winkler foundation, FDM Pasternak theoretical analytical solution Timoshenko are deduced calculate force, respectively. Typical parameters selected for design verification via methods GEO5, results show that calculated values basically consistent those using GEO5 software, which verifies feasibility methods.
