“…For a fully composite panel, the entire panel acts as a single unit in bending and the flexural design of fully composite panels can be considered as I-shaped section applying transformed section method (PCI Sandwich Wall Committee 1997). There are numerous techniques, for instance the shear connection between the outer face sheets, for ensuring linear composite behavior in the cross sections (Benayoune et al 2008;Shams et al 2014). To consider the importance of bond behavior between prefabricated concrete, epoxy bond as an adhesive material was also tested for the U-U1 and U-G specimens.…”

Sandwich panels comprising prefabricated ultra-high performance concrete (UHPC) composites can be used as ecofriendly and multi-functional structural elements. To improve the structural and thermal performance of composite sandwich panels, combinations of UHPC and expanded polystyrene (EPS) beads were investigated. High-performance expanded polystyrene concrete (HPEPC) was tested with various EPS bulk ratios to determine the suitability of the mechanical properties for use as a high-strength lightweight aggregate concrete. As a core material in composite sandwich panels, the mechanical properties of HPEPC were compared with those of EPS mortar. The compressive strength of HPEPC is approximately eight times greater than that of EPS mortar, and the thermal conductivity of approximately a quarter that of EPS mortar. The structural behavior of composite sandwich panels was empirically analyzed using different combinations of cores, face sheets, and adhesive materials. In the flatwise and edgewise compression tests, sandwich panels with HPEPC cores had high peak strengths, irrespective of the type of face sheets, as opposed to the specimens with EPS mortar cores. In the four-point bending tests, the sandwich panels with HPEPC cores, or reinforced UHPC face sheets combined with adhesive mortar, exhibited higher peak strengths than the other specimens, and failed in a stable manner, without delamination.

“…Shear connector needs to have sufficient ductility to perform adequately. Benoyane et al [1] (2008) studied the flexural behaviour of pre-cast concrete sandwich composite panel having truss type shear connector. The flexural test results showed that the precast specimens had a load deflection profile similar to that of one way and two way slab.…”

“…The uncertain role of the shear connectors and the interaction between its various components have led researchers to rely on experimental investigations backed by simple analytical studies, and different Finite Element (FE) models can be found in the literature [7,10,14,[25][26][27]. Other mathematical models can be found in the literature about the relationships between displacements and interface stresses of elements composed of two identical isotropic outer layers and a more compliant inner interlayer [28,29].…”

A More Sustainable Way for Producing RC Sandwich Panels On-Site and in Developing Countries

Abstract:The purpose of this work is to assess if traditionally used welded connectors for joining the two skins of reinforced concrete (RC) sandwich panels, used as structural walls and horizontal structural elements, can be substituted with bent ones. In this way, the scope of the effort is to reduce drastically the energy required during manufacturing, thus having a much more sustainable building product. Wire mesh on site production, in fact, requires a large amount of energy for the welding process, as stated by several Environmental Product Declaration (EPD). In addition, the production of sandwich panels with bent connectors requires a low level of automation and no qualified labor allowing the diffusion in developing countries. The procedures used to execute the work were both experimental and numerical. Structural performances were examined by testing full-scale sandwich panels under (axial and eccentric) compression and flexural loads. Additionally, a Finite Element (FE) study was developed to investigate and to optimize the dimension of welded mesh and the number of connectors. The major findings show that it is possible to substitute welded connectors with bent ones without compromising the structural performance of the tested RC sandwich panels, thus having a more sustainable way for producing these last ones.
