“…Element types that include the infill steel plate, concrete panel, headed stud and reinforcing bar were reported in either prior finite element models of the C-SPW [8,9] or steel-plate composite shear wall [27][28][29], which has a similar construction to that of the C-SPW. Herein, a 4-node reduced integration shell element (S4R) is utilized to model the infill steel plate; an 8-node reduced integration solid element (C3D8R) is utilized to model the concrete panel; a 2-node linear beam element (B31) is utilized to model the headed stud; and a truss element (T3D2) is utilized to model the reinforcing bar.…”

The composite steel plate shear wall (C-SPW), composed of infill steel plate and reinforced concrete encasements, is widely used as a lateral load resisting system in high-rise buildings. The reinforced concrete encasement is connected to one or both sides of the infill steel plate using headed studs. Previous in vestigations have mainly focused on the seismic behaviour of C-SPWs and the bending failure of the connector, as explored in some experimental studies , are found before C-SPW achieve its target drift ratio. However, the behaviour of the headed stud, which plays an important role in the performance of C-SPWs, has been largely neglected. In this paper, a study of the tensile force and bending moment demands on headed studs in the design of C-SPWs is performed by using the finite element method. As the theoretical basis, the development, distribution and formation mechanisms of stud tension and bending moment are analysed. The effects of the headed stud diameter, number of headed studs, infill steel plate thickness, concrete panel thickness and panel aspect ratio on the stud performance are investigated. Based on this, available formulas for the tension and bending moment demands on headed studs in the design of C-SPWs are proposed.

“…Bruhl et al (2015a) developed 3D finite element models to predict the behavior and local failure of SC walls subjected to missile impact using LS-DYNA. Other researchers also conducted finite element (FE) modelling of SC walls for calculating in-plane and out-of-plane shear responses in LS-DYNA (Kurt et al, 2016;Epackachi, 2014;Epackachi et al, 2015bEpackachi et al, , 2015c.

“…Epackachi (2014) conducted FE modeling in LS-DYNA to obtain a well-predicted response to the peak shear force but underestimated the post-peak responses, in which a perfect bond between the steel faceplates and the infilled concrete was assumed. This research was continued by Epackachi et al (2015bEpackachi et al ( , 2015c and focused on both the pre-and post-peak responses of SC walls, considering the friction between steel faceplates and the infilled concrete, buckling of the steel faceplates, and foundation flexibility. ABAQUS was also used to develop models to simulate the out-of-plane and in-plane shear behavior of SC walls (Chaudhary et al, 2011;Varma et al, 2011b;Ali et al, 2013;Nguyen & Whittaker, 2017).…”

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.

“…Experimental studies have been conducted on the composite shear wall with encased steel plate by Dong et al (2015) and Wang et al (2018) . Analytical studies of the seismic performance of composite shear walls with double flat steel plates and filled concrete were conducted by Nie (2014), Nguyen (2017), Epackachi (2017), and Zhao et al (2016) . Seismic performances of composite shear walls with double corrugated steel plates skin were studied by Hossain (2016) and Rafiei et al (2017), and it was found that the increase in the yield strength of steel is more effective in enhancing the shear strength of the composite wall compared with the increase in the compressive strength of concrete.…”

In this paper, composite shear walls with different encased steel plates (flat, horizontal corrugated, and vertical corrugated) were tested and simulated by Abaqus to investigate the seismic behavior of corrugated steel plate concrete composite shear walls (SPCSWs). The failure characteristics, deformation and energy dissipation capacity, and stiffness and bearing capacity of the structures under low-frequency cyclic load were analyzed, and indexes of the seismic performance were obtained. The formulas of the shear-bearing capacity of steel plate concrete composite shear walls are suggested, and the shear-sharing ratio of each member is obtained. According to the obtained results, corrugated steel plates can bond with concrete well, and the bearing capacity of the vertical corrugated SPCSW are higher than that of the horizontal corrugated SPCSW. Compared with flat SPCSW, corrugated SPCSW has higher initial stiffness and lateral stiffness, better ductility and energy dissipation ability, and the degradation of bearing capacity and stiffness is slower. The shear-sharing ratio of a steel plate is larger than that of reinforced concrete in the flat SPCSW and the vertical corrugated SPCSW, the shear force shared by steel plate and reinforced concrete in horizontal corrugated SPCSW is basically the same. KEYWORDSbuckling, corrugated steel plate concrete composite shear wall, energy dissipation capacity, hysteretic curve, seismic behavior, shear bearing capacity 1 | INTRODUCTION For many years, shear walls have been widely used as an effective lateral force-resisting system for high-rise buildings in high-risk seismic regions.The reinforced concrete shear wall is one of the most widely used shear walls. But the past earthquake experience and previous research indicated that the traditional reinforced concrete shear walls at the bottom of high-rise buildings may display the undesirable performance when subjected to severe earthquakes. [1] The steel plate shear wall (SPSW) is an effective lateral force resisting system in which unstiffened steel plates are connected to the horizontal and vertical boundary elements on all sides of the plates. [2] With good ductility, light weight, high strength, and high stiffness, the SPSW has drawn many engineers' attention. [3] Berman (2011) [4] designed a series of SPSWs with different geometries and evaluated the seismic behavior using nonlinear response history analysis for ground motions representing different hazard levels. Pavir et al. (2017) [5] compared the performance characteristics of the coupled steel plate shear walls with different cross section dimensions and lengths for coupling beams. Zhao et al. (2017) [6] and [7] conducted the nonlinear push-over analyses and cyclic analyses on the flat SPSWs and the corrugated SPSWs. Hosseinzadeh et al. (2017) [8] investigated the effect of variation in the angle of trapezoidal plate on the behavior of corrugated SPSWs. It was found that the SPSW deformed greatly in the loading process, and the vertical load bearing capac...
