Research and application of high-performance double steel-plate reinforced concrete structures

Steel-plate reinforced concrete structure is another important composite structure form after steel-concrete composite beams and concrete-filled steel tube columns. It is mainly suitable for walls, plates, shells, and other components, with flexible structural form, satisfied comprehensive performance advantages, and wide application value. The main research progress and engineering application of double steel-plate reinforced concrete structure were introduced, focusing on its application in shear wall structures, immersed tunnels, long-span bridge towers, and protective structures. The characteristics and advantages, theoretical and experimental research, and their application in typical engineering projects of various steel-plate reinforced concrete shear wall structures, compartment steel-plate reinforced concrete immersed tunnel structures, steel-plate reinforced concrete bridge tower structures, and steel-plate reinforced concrete ice wall structures were introduced. Based on the related research and applications, the advantages of steel-plate reinforced concrete structures in mechanical performance, service function, and construction were demonstrated adequately. The in-plane and out-plane mechanisms and failure modes of various types of structures were revealed. In addition, the design methods for interfacial connection between steel plate and concrete, bearing capacity, and stiffness were proposed. Finally, the application prospect of steel-plate reinforced concrete structure in other engineering fields such as modular construction of nuclear power plants, tunnel lining, marine platforms, and the problems that still need to be further studied in theory and practice were proposed.
