Composite Behavior of Insulated Concrete Sandwich Wall Panels Subjected to Wind Pressure and Suction

A full-scale experimental test was conducted to analyze the composite behavior of insulated concrete sandwich wall panels (ICSWPs) subjected to wind pressure and suction. The experimental program was composed of three groups of ICSWP specimens, each with a different type of insulation and number of glass-fiber-reinforced polymer (GFRP) shear grids. The degree of composite action of each specime...

Structural performance of near-optimal sandwich panels with corrugated cores

An experimental and computational study of the bending response of steel sandwich panels with corrugated cores in both transverse and longitudinal loading orientations has been performed. Panel designs were chosen on the basis of failure mechanism maps, constructed using analytic models for failure initiation. The assessment affirms that the analytic models provide accurate predictions when fai...

Uncertainties in structural dynamics for composite sandwich panels

This paper concerns uncertainties in structural dynamics for composite sandwich panels constituted of two thin carbon-resin skins and one high stiffness closed-cell foam core. Each skin is constituted of two unidirectional plies [60/-60]. Such light composite sandwich panels, manufactured with a same process, generally present a significant dispersion for their Frequency Response Functions (FRF...

Adjusted Density High-strength Concrete Using Expanded Polystyrene Beads

This paper reports the results of an experimental investigation into the effects of incorporating varying amounts of expanded polystyrene beads on the engineering properties of high-strength concrete. It was observed that a density reduction of 8.3% caused compressive strength, tensile strength and modulus of elasticity to reduce by 48%, 39% and 15%, respectively. Drying shrinkage was marginall...
