SUMMARY:

The application of Sandwich Panels has been significantly increasing in the Brazilian construction industry in recent years, with more significant usage in residential buildings. However, these construction elements are often employed without a proper understanding of their structural behavior due to the absence of regulatory standards and reliable calculation methods. Therefore, in order to assess the structural behavior of these panels under compression forces, a 3D nonlinear Finite Element model was developed in the ABAQUS software. This model was validated through experimental tests, demonstrating its capability to satisfactorily simulate the structural behavior of sandwich panels subjected to eccentric compression loads and providing reliable estimates of their strength capacity. In addition, a parametric study was conducted to evaluate the influence of insulation layer geometry, spacing, and diameter of the metal meshes on the panel's strength capacity. Finally, an equation for calculating the ultimate load of the sandwich panel subjected to eccentric compression loading was proposed.
