“…Fernando et al [7] investigated the structural feasibility of an EPS based lightweight concrete full scale sandwich wall panel, which achieved a failure stress of 3.89 N/mm 2 . Ridha et al [8] studied the compressive and flexural behavior of composite panels made of lightly profiles steel skins and lightweight concrete, which showed good ductility in flexure. Hou et al [9] studied the flexural behavior of four sandwich panels with reinforced concrete wythes (connected with diagonal steel bars) and inner flat or ribbed EPS layer.…”

This research study aims at developing and investigating the mechanical and thermal properties of lightweight sandwich wall panels with good thermal insulation properties to reduce electric power for cooling of buildings. Within this study, several thermal insulation sandwich wall panels with two outer lightweight concrete layers and inner expanded polystyrene layer were developed and tested. Test parameters included the type of the outer concrete layers and the effect of using glass fiber reinforced polymer (GFRP) shear ties to connect the outer layers. Different ratios of polystyrene beads and vermiculite aggregates (53, 68 and 84% by volume of the natural coarse aggregates) were used to replace the natural coarse aggregates in the two outer concrete layers for better insulation properties and to develop lighter panels. Test results showed that using the GFRP shear ties was effective to connect the two outer layers of the panels. The results also revealed that increasing the amount of the polystyrene beads and the vermiculite aggregates decreased the thermal conductivity, the density, and the compressive strength of the panels. These values ranged from 0.41 to 0.25 W/m.K, 596 to 486 kg/m3, and 4.21 to 2.02 MPa respectively, for the panels with polystyrene beads. For the panels with vermiculite aggregates, these values were 0.46 to 0.34 W/m.K, 646 to 626 kg/m3, and 3.14 to 1.96 MPa, respectively. The results showed that the panels with polystyrene beads were stronger, lighter, and had better thermal properties. Using the developed panels will help to reduce the self-weigh of buildings resulting in smaller structural elements. In addition, the excellent thermal properties of the developed panels are expected to reduce power consumption and develop more sustainable buildings.

While introducing the novel structural method, this paper compares the behavior of composite panels comprised of cold-rolled galvanized sheets infilled with the foamed concrete and the fire-resistance polyurethane foam. A series of axial and bending tests are carried out on the composite panels with mentioned fillers; also, the function of the wire mesh and surrounding cold-rolled galvanized sheets with different thicknesses and different fillers are investigated in an attempt to know the effects of mentioned sheets on the final strength. The results show that applying the fire-resistance polyurethane foam performs better in enhancing the bending and the axial strength of composite panels in comparison with the foamed concrete filler. By this combined system with foamed concrete as infilling material, the cold-rolled galvanized sheets, which endure low bending and axial tension, have been able to withstand bending and axial load around 1.92–4.08 N/mm2 and 0.98–1.074 N/mm2, respectively. In addition to the aforementioned composite system, those panels with fire-resistance polyurethane foam as infilling material, apart from the greater lightness, around 40% lighter, have been able to withstand more with approximately 50% and 10% higher bending and axial load, respectively.

This study covered numerical analysis models of lightweight concrete panels with a variety of thicknesses and door opening positions. The objective of this study was to determine the influence of the dimension of lightweight concrete nonstructural panels with door openings in resisting static lateral loads. The lightweight concrete became generally used since its’ effectiveness in reducing gravity loads. Therefore, the lateral deformation of buildings due to the earthquake became smaller. However, the behavior of the lightweight concrete panels as non-structural elements still needed to be explored, especially under influence of structural elements when an earthquake occurred. There were three variations of the door opening positions on the panels. The varied thicknesses were 40 mm, 50 mm, and 60 mm with and without the addition of wire mesh reinforcement. The panels were subjected to increased static monotonic loads until the panels were collapsed. The analysis results were the relation curves of loads and deformations, and the shapes of deformation that occurred on each model. The analysis results of each panel showed different behaviors and values. In general, the variation of thickness resulted in the conclusion that the thickest panels were able to resist higher loads. The use of wire mesh affected significantly panel behavior. The panels with wire mesh became more rigid so that the resisted loads were higher, but the deformation became smaller, and vice versa while the panel without a wire mesh resisted lower loads but the deformation became larger.
