| Structural Concrete Insulated Panel (SCIP) is a relatively new construction technology
which is an alternative to the traditional wood framing for residential and low-rise commercial
buildings. A typical SCIP is composed of an Expanded Polystyrene (EPS) core with a thin layer
of concrete on each side. A concrete layer houses a galvanized steel mesh which are connected
to each other with shear connectors also known as truss diagonals. Past research has
demonstrated that SCIPs offer good structural resistance, thermal and acoustic insulation
properties. SCIPs are generally unknown to practicing structural engineers. Most engineers find
it difficult to predict the axial, flexural, and shear capacities of SCIPs. This research presents
analytical and some experimental investigation of SCIPs that utilize precasting and modular
construction. Simplified flexural analysis in-line with the principles of reinforced concrete
design is proposed for the experiments previously conducted at Idaho State University on full-
scale SCIPs. Analytical results are compared with the experimental data to validate the analysis
approach for SCIPs with different spans, materials properties, and thicknesses. Due to lack of
experimental data on shear strength of SCIPs, two specimens were tested under direct shear
loading in the structural laboratory (SLAB) at Idaho State University. The panels exhibited
substantial deformation prior to failure. The failure mechanism under direct shear loading was
observed to be shear-compressive for both panels. Upon inspection of the tested panels,
significant buckling of diagonal connectors was observed. Experimental results from the shear
tests were used to generate simplified analytical approaches for prediction of shear strength of |
