The idea of a construction model that can add sustainability, lightness, significant stiffness, and strength to the precast industry has contributed to the advancement in research on sandwich panels. These panels are manufactured and improved to obtain a high strength-to- weight ratio, stiffness-to-weight ratio, and other construction advantages such as fast assembly, cost reduction, and good insulation properties. This dissertation presents an axial compression analysis of sandwich panels with self-compacting concrete, EPS, and reinforcement to offer to those interested in alternative construction methods information on a viable solution advantageous at various levels that can be adapted and equally suited to their construction needs. This work presents a summary of the various applications, followed by a review that describes the influence of each component of the panel in its structural capacity. The advantagesand disadvantages of the panels are addressed, accompanied by several studies performed applying alternative materials and geometries. A laboratory study was conducted with six prototypes, where the influence of slenderness, materials used, and geometry on the failure mode to axial compression was evaluated. Finally, a brief conclusion of what was covered throughout the dissertation is presented. Keywords: Sandwich panel. Experimental analysis. Precast concrete element. Axial compression. Constructive system.
