Abstract
This dissertation presents a structural evaluation of Concrete-Expanded Polystyrene (CEPS) sandwich panels for slab applications through the finite element analysis
approach. It is based on the experimental work previously conducted at University of California, Irvine (UCI). These panels comprise of expanded polystyrene foam sandwiched between concrete-steel panels.
This research uses structural software Strand7, which is a numerical approach based on finite element method, to predict the load deformation behaviour of the CEPS sandwich
slab panels. The concrete facings of the panel and expanded polystyrene (EPS) foam are modeled using brick elements whereas steel wire mesh is represented by cut-off truss
elements. The model was analyzed by non linear static analysis. Finite element results are compared with experimental data to validate the numerical approach used. The verified model is used for parametric study to understand the behaviour of CEPS panels under different load combinations.
This research shows that a simple Strand7 finite element model can be used for the analysis of CEPS sandwich panels for slab applications. Analytical results using FEA
show good correlation with the experimental results. Furthermore, the use of foam in the middle of the sandwich panel will reduce the weight of the structure and also acts as insulation against thermal, acoustics and vibration. The design chart developed for various thicknesses of CEPS slab panel can be used for low cost residential and commercial structures.
