“…Due to its great ultimate strength-to-cost performance [14], SCS shows adaptable potential applications in offshore structures. SCS composites have been used for gravity-based Arctic offshore caisson structures (GBS) [15,16], LNG or oil containers [17], undersea oil production modules [18], immersed tube tunnel construction [19,20], shear walls [21], third-generation nuclear power plants [22,23], offshore decks [18], and bridge decks [18]. The key benefits of SCS composite structure are: (1) steel plates play a role in flexural reinforcement and suggest a lasting formwork that reduces site labour work and improves construction effectiveness [14]; (2) steel plates can be simply cut to any form, and the shear connectors can be quickly connected, reducing the work required for the cutting, bending, and tying of the reinforcement bars; and (3) steel plates are impermeable and benefit impact-and blast-resistant films.…”

Bottom slamming loads cause considerable local damage to a ship’s body and reduce the ship’s structural performance against harsh sea waves. Although extensive studies have worked on stiffening elements to compensate for local damage due to slamming loads, few studies have concentrated on the ship’s body itself while using new generations of composite plates. Accordingly, a numerical study is conducted to determine the effect of using ultra-lightweight high-ductility cementitious composite in steel–concrete–steel (SCS) composite plate to mitigate bottom slamming loads. A large-scale model of the ship using SCS composite plates is modelled in Abaqus software, and fluid–solid (FSI) interaction is precisely modelled using the Coupled Eulerian–Lagrangian (CEL) method. The results show that using the CEL method with a large-scale 3D model precisely simulates FSI by providing a 6.5% deviation from the experimental result. Moreover, using an SCS plate when considering ultra-lightweight high-ductility cementitious composite results in a considerable reduction (around 95%) in the maximum strain of the ship body and, accordingly, reduces local damage so that, although about 22% of the strain of the outer layer is transferred to the inner part of the ship body containing only steel plate, almost 0% stress transfer is observed for the SCS-based ship’s structure.

Many bridges suffer from aging and deterioration problems and need to be strengthened. PSWR-PUC is an emerging structural strengthening technology that enhances the load-bearing capacity of concrete bridges by embedding prestressed steel wire ropes into polyurethane cement. This paper focuses on investigating the shear reinforcement effectiveness of PSWR-PUC. Firstly, the composition of PSWR-PUC is introduced. Subsequently, two T-beam bridges in similar service condition are selected, and shear strengthening schemes involving PSWR-PUC and externally bonded steel plates are devised. Lastly, static loading tests are conducted, and the deflection and strain data of the two bridges before and after reinforcement intervention are analyzed. The results indicate that both strengthening methods improve the bridge load-carrying capacity. However, compared to the bridge strengthened with the externally bonded steel plate method, the deflections in the bridge strengthened with PSWR-PUC decreased by 36.8% and 42.1%, the strains decreased by 18% and 23%, and the shear stiffness was improved to a greater extent. These results verified that the PSWR-PUC strengthening method is effective for improving structural capacity and performance. This study will contribute to an in-depth understanding of the performance characteristics and application scope of PSWR-PUC shear strengthening technology, and it provides a scientific basis and guidance for practical engineering applications.

“…For partial composite SCS beams, bondslip appear between concrete and steel plate, which relieves the loading on the steel plate and weakens the ultimate resistance of the structure [24]. Based on Eurocode 2 [25] and ACI 349 [26] for RC beams, bond-slip effect has been considered [27,28] to predict transverse shear resistance of SCS beams. As regard SCS panels, loads are transferred in three directions and all the materials are under tri-axial stress states.…”
