The continuous awareness against the limited earth resources and global warming effect has urged the demand upon the technology that consumes less energy and dependencies on the natural resources. The progressive research upon this issue has initiated the idea of using Precast Lightweight Foam Concrete Sandwich Panel (PLFP) as an alternative to Industrialize Building System (IBS). The PLFP consist of two wythes that enclosed a layer of polystyrene which functioned as insulation layer. Steel bar of 9 mm will be used for the horizontal and vertical reinforcements and 6 mm steel bent at 45° will be used as shear truss connector. The purpose of this paper is to study the structural behavior of the PLFP panel under the eccentric load. The study will involve the relationship between the density, slenderness ratio, compressive strength, crack pattern and the comparison of the structural behavior of PLFP under axial and eccentric load. The results from testing the two samples of PLFP panel under axial and eccentric load showed that PLFP will have lower strength capacity when tested under eccentric load. Consideration on this particular aspect will increase the reliability on the PLFP application in the construction field.
