Introduction The mechanical performance of metallic sandwich panel with lattice-based core superiors the stiffened foam based concept under major loading conditions [1-2]. Moreover, the advanced concepts were investigated, e.g., fiber reinforced composites for sandwich panels [3]. However, such lattice-based structures are still unconventional for analys .

A space between the outer sheets of the sandwich is filled with concrete. The considered plate has large dimensions within standard range in order to provide meaningful data for industrial case and capture geometry nonlinearity in stress analysis. The ultimate compressive load is estimated by the simulation procedure using Abaqus FEA software. The result is that proposed structure shows 1.4 higher ultimate load in comparison with conventional concrete plate reinforced by steel bars, while the metal consumption is identical.
