In this paper, experimental and simple analytical studies on the structural behavior of Precast Foamed Concrete Sandwich Panel(PFCSP) were reported. Full-scale tests on six PFCSP panels varying in thickness were performed under axial load applications. Axial load-bearing capacity, load-deflection profiles, load-strain relationships, slenderness ratio, load-displacement, load-deformation,typical modes of failure and cracking patterns under constantly increasing axial loads were discussed. Nonlinear Finite ElementAnalysis (FEA) using LUSAS software to investigate the structural behavior of PFCSP was contacted. The computed ultimatestrength values using American Concrete Institute equation (ACI318) and other empirical formulas developed by perviousresearchers which applicable to predict the ultimate strength capacity of sandwich panels were compared with the experimental testresults and FEA data obtained; therefore, very conservative values resulted, a significant agreement with the FEA data that presenteda high degree of accuracy with experiments and an increase in slenderness function.
