Static response of thermally loaded sandwich beams with confined horizontal displacements of faces at the supports

Abstract

Abstract. The paper examines the problem of the influence of restrictions on freedom of horizontal displacements in thermally loaded sandwich beams. The classical theory of sandwich beams and panels with thin facings and a soft core has been applied. It was assumed that the cross-section of the beam could be asymmetric geometrically and materially. The beam has vertical supports and additional horizontal supports limiting the freedom of horizontal displacements. The supports are linearly elastic and the rigidity of the upper and lower support can be arbitrary. The static problem of single-span beam with support conditions identical at both ends of the beam was solved in the paper. Each of the sandwich facings has been subjected to temperature change. The derived formulas were used in the example illustrating the importance of the problem.
