Papers by Keyword: Two Layer Beam

Abstract: We have already considered the problem of joint work of structure, foundation slab and basis in [1, 2] (two-layer beam or slab on elastic basis). The distinctive paper is devoted to analysis of two-layer beam-strip on elastic basis, which corresponds to the problem of the plane deformed state. Nonlinear dependence of internal forces on structure height is presented.

Abstract: This paper develops a spectral element model for elastic-elastic two-layered beams. First, the axial-bending coupled equations of motion for an elastic two-layer laminated beam are derived. The spectral element model is then formulated by using the wave solutions satisfying governing equations in frequency-domain as the frequency-dependent shape functions. The spectral element model is finally applied to a cantilevered elastic-elastic two-layered beam as an illustrative problem. The high accuracy of the present spectral element model is verified by comparing the SEM results with those obtained by conventional FEM.
