“…Seeking to provide a modeling recommendation for TFSCWs analysis and design under the influence of thermal load, in 2012, Varma et al Varma et al (2012) summarized findings from several work program types of research TFSCWs under various types of loadings. Experimental and analytical research indicated that additional concrete cracking and flexural stiffness reduction occurred with the accident thermal conditions.…”

Recently, the concrete-filled twin-layer steel-sheet composite wall systems (TSCWs) have become recommended by the engineers in the modern structures, since it has high energy absorption, ductility, and capacity compared to the corresponding conventional wall systems. Therefore, this paper presents and discusses the literature of researches particularly concerning this type of composite wall system. The review includes 80 papers that investigated the performance of TSCWs. These investigations classified TSCWs into two types: twin-layer flat steel sheet composite wall systems (TFSCWs) and twin-layer profiled steel-sheet composite wall systems (TPSCWs). The classification of these two types of TSCWs was based on the form of the sheeting as well as on the type of applied load. This classification introduced comprehensive mapping tables on the study details, loading, infill material, and interaction concept. Furthermore, the findings from this literature review are discussed, and the research gaps are summarized for each TSCW type, including the impact of providing an opening on the TSCWs performance.

“…SC structures are composite structures in which thick concrete is placed between thin steel plates; the steel plates thus replace the rebars in RC structures to give the required in-plane and out-ofplane strength for members. They are expected to work as a mould (Akiyama et al, 1989;Liew et al, 2017;Ozaki et al, 2004;Varma et al, 2012). In addition, SC structures have 1•5 times the ductility of RC structures and offer advantages in terms of the generated fragments due to an explosion under a blast load (Kang, 2012).…”

An analytical study using a non-linear finite-element method was carried out to evaluate the effect of the shape and spacing of shear studs on the behaviour of steel-plate-concrete walls subject to blast loads. The size of the analytical model was determined by reference to an existing literature review and code requirements (Kepic-SNG). The analytical model was validated against experimental results. The behaviour of a wall subject to blast loading was then analysed for various stud spacings and shapes. As found in previous research, the maximum deflection increased as the spacing of studs increased and the time when the maximum deflection occurred was delayed. Improved studs were found to be effective in reducing displacement when arranged at lengthwise spacings of 100 mm or more.

“…Similarly, the US-APWR ® (DCD, 2013) power plants being considered for licensing in the United States utilize SC walls for the entire CIS. Future nuclear power plants, including advanced light water reactors (ALWRs) and small modular reactors (SMRs), are considering SC walls for achieving modularity and expediting the construction schedule while improving structural strength, safety, and resilience for seismic load combinations and accident thermal load combinations (Varma et al, 2015).…”

“…The SC wall system also eliminates the need for conventional steel reinforcement (rebars), which reduces congestion-related issues and can further expedite construction. Additional advantages of SC construction include modularity and construction schedule (Varma et al, 2015), structural strength and safety for seismic and accident thermal loading combinations (Sener et al, 2015a;, and resilience to impactive and impulsive loading. These are all discussed in Varma et al (2015) and not repeated here.…”

Steel-plate composite (SC) walls are comprised of concrete walls sandwiched between steel faceplates located on the exterior surfaces. These faceplates are anchored to the concrete infill using steel anchors and connected to each other using ties. SC walls have been used extensively in the third generation of nuclear power plants and are also being considered for small modular reactors (SMRs) of the future. The American Institute of Steel Construction (AISC) has published Supplement No. 1 to AISC N690, which includes Appendix N9 for the design of SC walls in safety-related nuclear facilities. This paper presents the minimum requirements for SC walls and the section detailing provisions from Appendix N9 along with their basis. The minimum requirements include requirements for minimum and maximum SC wall thickness, faceplate thickness, and steel and concrete material strengths. The provisions of Appendix N9 are applicable to SC walls that satisfy these minimum requirements. The design provisions account for the effects of interaction between out-of-plane shear demands (in both x- and y-directions) and the corresponding interfacial shear demands while accounting for the differences in behavior between yielding and nonyielding steel anchors and ties as classified by AISC N690 Supplement No. 1.
