“…The structure provides the advantages of reinforced concrete (specifically, strength and stiffness) thanks to the optimal use of concrete and steel. Moreover, the external steel plates increase the stiffness, the sustainability, and the strength under some extreme solicitations [9][10][11][12] and are used as lost formwork, which can be prefabricated. SCS structures are thus considered modular structures [13][14][15] and are gaining increasing interest in construction.…”

Steel–concrete–steel (SCS) sandwich structures have gained increasing interest in new constructions. The external steel plates increase the stiffness, the sustainability, and the strength of the structures under some extreme solicitations. Moreover, the use of these plates as lost prefabricated formwork makes SCS structures modular, enabling higher construction rates. However, for a better understanding of the complex behavior of these structures up to failure, refined numerical simulations are needed to consider various local phenomena, such as concrete crushing in compression and interface interactions. Indeed, the highly non-linear steel–concrete interaction around the dowels is the key point of the composite action. In this contribution, a refined methodology is first proposed and applied on a push-out test. It is especially demonstrated that a regularization technique in compression is needed for the concrete model. Interface elements are also developed and associated with a nonlinear constitutive law between steel connectors and external plates. From this refined methodology, simplified numerical modeling is then deduced and validated. Directly applied to an SCS wall-to-wall junction, this simplified strategy enables the reproduction of the overall behavior, including the elastic phase, the degradation of the system, and the failure mode. The response of each component is particularly analyzed, and the key points of the behavior are highlighted.

“…The concrete cracking occurred in the center of the heated region because of the thermal gradient through the SC wall depth. Booth et al (2015) also studied the out-of-plane flexural response of SC walls subjected to accidental thermal and mechanical loading in four full-scale beam tests, which showed that thermal loads reduce the out-of-plane flexural stiffness of SC walls. Large scale experiments referring to inelastic behavior are very important for fully studying the shear response of SC walls for use in civil engineering and safety-related nuclear structures.…”

“…Some relevant numerical studies have been performed during the past twenty years (Braverman et al, 1997;Emori, 2002;Varma et al, 2011b;Kurt et al, 2013Kurt et al, , 2016Epackachi et al 2015a;Sener et al, 2015Sener et al, , 2016Booth et al, 2015;Bruhl et al, 2015b). Braverman et al (1997) used ANSYS to develop a model to simulate the behavior of SC walls under monotonically loading, in which a bilinear stress-strain curve and a linear elastic-perfectly plastic model were applied to represent the uniaxial behavior of the steel faceplates and the compressive stressstrain relationship of the infilled concrete, respectively.…”

Reverse cyclic lateral testing was undertaken to investigate the seismic behavior of 1/4 scale steel-plate concrete (SC) composite walls. The experimental program involved seven SC wall pier specimens. A new chamber structure is proposed, using steel diaphragms to connect the two steel faceplates to each other and to divide the SC wall pier into two parts. Conventional wall specimens failed mainly by tensile fracture of the concrete at the junction of the wall side and wall base, crushing of the concrete at the toe of the wall, or buckling of the steel faceplate. Tearing of the welded joints at the steel faceplates and steel diaphragm, buckling of steel, steel diaphragms being pulled out, tensile fracture and crushing of the concrete were the main failure modes of the chamber structure walls. A parametric numerical analysis in ABAQUS was developed to investigate the effects of the stiffening rib, steel web amount, material strength, shear-span ratio, and axial compression ratio on the seismic response of SC walls. The chamber structure of the SC wall piers can improve the peak load, ductility, and energy-dissipating capacity. The steel faceplate thickness and stiffening ribs can improve the behavior of SC wall piers.

“…C oncrete-filled, sandwich steel panel walls (CFSSP-Walls) have been the subject of extensive research in recent years, with an emphasis on their potential application in nuclear power plants or high rises (e.g., Oduyemi and Wright, 1989;Wright et al, 1991aWright et al, , 1991bXie and Chapman, 2006;Eom et al, 2009;Ramesh, 2013;Zhang et al, 2014;Sener and Varma, 2014;Varma et al, 2014;Epackachi et al, 2014;Sener et al, 2015;Epackachi et al, 2015;Booth et al, 2015;Kurt et al, 2016;Seo et al, 2016;Alzeni and Bruneau, 2017;Polat and Bruneau, 2017). Referred to as "composite plate shear walls-concrete filled (C-PSW/ CF) by the AISC Seismic Provisions (AISC, 2016), and steel concrete (SC) walls in some of the above-cited publications, these walls consist of dual-steel-plate "sandwiching" a concrete infill.…”

Flexure-dominated, concrete-filled sandwich steel plate walls (CFSSP-Walls) have been studied experimentally by various researchers using a small number of cross-sections and wall aspect ratios. Using these past results to calibrate finite element models, the expected behavior of CFSSP-Walls having different geometries and cross-section properties is investigated here using finite element approaches. Results obtained show that the plastic moment can be used to conservatively predict maximum flexural strength in all cases considered and to provide valuable insights into stress and strain demands at various points during nonlinear response. Results also provide quantification of the contribution of concrete infill on the wall effective stiffness, assessment of wall ductility having a failure criteria based on cumulative plastic strain at steel plate fracture, and effect of wall flange width on the wall behavior of T-shaped sections.
