Abstract

Sandwich panels are composed of two thin face layers and a lightweight core between them. Panels are used to carry large bending moments and axial forces, which capacity is reduced, if imperfections, for example initial deflections or transverse loads, appear in the face layers. At intermediate supports the panel is stressed by a high bending moment and, in addition, by a concentrated lateral support reaction. The strength against the simultaneous bending moment and support reaction depends on the bending stiffness and on the bending and buckling strength of the face and on the compressive strength of the core. The paper 'studies factors having influences on the behaviour and on the failure modes of multispan sandwich panels. Also proposals to estimate the strength at the serviceability and at the ultimate limit states are presented.

Analysis and Design of Continuous Sandwich Beams

Saint Louis, Missouri

Sandwich panels are composed of two thin face layers and a lightweight core between them. Panels are used to carry large bending moments and axial forces, which capacity is reduced, if imperfections, for example initial deflections or transverse loads, appear in the face layers. At intermediate supports the panel is stressed by a high bending moment and, in addition, by a concentrated lateral support reaction. The strength against the simultaneous bending moment and support reaction depends on the bending stiffness and on the bending and buckling strength of the face and on the compressive strength of the core. The paper 'studies factors having influences on the behaviour and on the failure modes of multispan sandwich panels. Also proposals to estimate the strength at the serviceability and at the ultimate limit states are presented.
