Elastic beam resting on Vlasov elastic foundation and subjected to an external concentrated load

Keywords: elastic beam, Vlasov foundation, cross-sectional forces, beam deflection, displacement disappearance function
Abstract:

The paper presents the problem of bending of a beam uniformly loaded along its entire length, resting freely
on an elastic Vlasov foundation with an additional external load G applied to the ground at a distance a from
the beam end. The given example is a special case of a beam resting freely on an elastic foundation, which
is present in many cases of building practice. The paper considers an approximate solution for the influence
of an additional load G on the deflection and cross-sectional forces of a beam resting freely on Vlasov elastic
subsoil. Graphs of a deflection of the beam and of a soil surface layer beyond the limits of the beam, as
well as graphs of bending moments and transverse forces in the beam have been presented. The influence of
an additional load applied in a distance a on the deflection and cross-sectional forces in the beam has been
investigated.
