“…The study showed that, for the given slenderness ratios, the fully profiled sheets may be regarded as fully effective with the compressive resistance of the sheets equal to the yield strength. For the lightly profiled sheets, the model of Pokharel and Mahendran (2003) was found to give the best results when the depth was in excess of 3mm, while the formulas of Stamm and Witte (1974) were ideal for rib depth below 3mm. These methods were therefore chosen for the optimization model.…”

A series of studies have been undertaken to quantify potential steelwork and embodied carbon savings in single-storey industrial buildings with long span sandwich panel roof cladding. It was found that trussed-roof frames with north lights offer the greatest potential steelwork saving (38%-60%) against traditional portal frame construction when used with long span panels. However, in order to achieve the necessary span between adjacent frames, the structural performance of the sandwich panels needed to be improved. A subsequent study was undertaken to develop revised specifications for long span roof sandwich panels to increase their spanning capability, while minimizing the increase in embodied carbon. The mechanical resistance of the panels was evaluated using a combination of theoretical analysis and structural testing and a Pareto-optimal set of solutions was found. Finally, the optimized structure-envelope assembly was reviewed holistically in terms of its embodied carbon. The results showed that savings of up to 7.3% may be achieved for the frame when compared against traditional portal frame construction.

“…Driven by the concept of carbon peaking and carbon neutrality goals, the proposal and application of assembled concrete composite structure systems further highlight the advantages of green, energy-saving and low-carbon industrialized building [10][11][12]. In recent years, innovative precast concrete composite structures such as precast concrete sandwich structures [13][14][15], steel-concrete composite structural walls with internal bracings [16], ceramsite concrete hollow block infilling wall structures [17], polystyrene plate sandwich concrete infilling structures [17][18][19][20], and precast concrete wall with X-shaped steel plate bracings [21] have flourished. The above precast concrete composite structures are all assembled by precast concrete components through horizontal joints and vertical joints [22][23][24][25][26][27].…”

In this paper, a novel precast concrete composite wall connected by tooth groove and grouted sleeve was introduced, which is produced in factories by means of structure-insulation integrated prefabrication, and the prefabrication and assembly process were presented minutely. To verify the feasibility and reliability of this novel tooth groove and grouted sleeve connection method and explore the joint connection performance and the seismic performance of the precast concrete composite wall connected by tooth groove and grouted sleeve, low-cyclic reversed loading tests with an axial compressive ratio of 0.1 were performed on two full-scale precast concrete composite walls. Moreover, the failure mode, hysteretic curve, skeleton curve, stiffness degradation, displacement ductility, energy dissipation capacity, and reinforcement strain were comprehensively discussed. The research results showed that under the vertical axial load and low-cyclic reversed load, the distributed reinforcements in the wall panel only played a structural role, while the connecting reinforcements at horizontal joints can always effectively transfer stress without bond failure, and the tooth groove and grouted sleeve connection performance was reliable. In addition, the hysteretic curves of the precast concrete composite wall connected by tooth groove and grouted sleeve were full, showing good ductile deformation capacity and energy dissipation capacity. In general, the precast concrete composite wall connected by tooth groove and grouted sleeve not only possessed favorable seismic performance but also showed obvious advantages such as green energy saving, high assembly rate, and less on-site wet operation, which can be applied to practical engineering under reasonable design.

A sandwich panel is a lightweight structure, economical and having low thermal conductivity. It is made up of three layers in which the middle layer is called core which is bounded with thin layers at top and bottom called faces. Generally, the core has relatively low-density which makes it lightweight. The buckling load analysis of sandwich panel having isotropic core and orthotropic faces is studied for different support conditions using the FE based software ABAQUS. The FE model is validated with suitable published results. Then it is used to find critical buckling load of sandwich panel with isotropic core and orthotropic faces. Many new results have been presented for different thickness, end conditions, aspect ratio, etc.
