“…Comparing to 1.0 mm SSPs thickness, 0.8 mm was preferred due to the negligible difference in capacity. Similarly and most recently, Labib-Zadeh and Hamidi Labibzadeh and Hamidi (2019) presented a comparison study between capacities of the TPSCW system and the composite steel plate shear wall (CSPSW) system. To that end, 22 verified FE models of the TPSCWs system, includes the same concrete panel, SSPs thickness, fewer fasteners, and without reinforcement bars, were compared with CSPSWs type of walls.…”

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.

“…(9), ε p is the maximum tensile strain of concrete and ε t denotes the concrete tensile strain [46][47][48]. The optimum values of the plasticity input parameters of the CDP model including the dilation angle (ψ), eccentricity (ϵ), the ratio of the biaxial compressive strength to the uniaxial compressive strength of the concrete ( f b0 / f c0 ), the ratio of the tensile meridian to the compressive meridian in the deviatoric plane of the yield surface (K c ), and viscosity (μ) were introduced in Table 1 [49][50][51][52][53][54][55][56][57][58][59][60][61].…”

This paper is the first to present the results of a numerical comparison between the performances of two newly developed concrete columns namely: multi-tied spiral transverse reinforced (MTSTR) column and concrete-filled steel tube (CFST) column under eccentric compressive loads. The behavior of MTSTR columns under eccentric loads has not been studied until today and also this behavior is not compared to that of the CFST columns. The numerical models of these columns were constructed using the nonlinear finite element method and validated against the previously published experimental data in the literature. Concrete damage plasticity model and elastic-perfect plastic model were used to simulate the behavior of concrete core and steel of the columns, respectively. This provides the capability of modeling of the nonlinear large deformations of the columns. The obtained results show that the MTSTR columns can provide greater load carrying capacity, ductility, and energy absorption with slightly lower initial stiffness than the CFST columns under the same eccentricities. For instance, the load-carrying capacity of MTSTR column is 18 percent greater than that of the CFST column when the load eccentricity is 100 mm. In case of 100 mm eccentricity, the ductility of the improved version of the MTSTR column proposed in this study is 30 percent greater than CFST one.

“…In recent years, numerous studies have been conducted to investigate the performance of various structures derived from the different classes of CSW; some of which have led to the introduction of specific models of such systems. For example, shear walls infilled with concrete having bundled channels [36], CSW with concrete-filled steel tube (CFST) columns connected to beams only [37], precast slender CSW with CFST boundary elements [38], multi-partition CSW [39], RC wall web having square CFST columns as boundary elements incorporating CFRP-confined concrete core [40], encased steel plate-reinforced gangue CSW [41], double-skin profiled wall [42], CSW infilled with concrete having dual steel plates with vertical stiffening steel plates [43], CSW with high-strength concrete and steel rebars with consideration of concrete-encased CFST columns as boundary elements [44], and CSW with FRP-confined concrete cores [45] or enhanced C-channels [46] can be mentioned.…”

This article presents a novel approach to estimate the flexural capacity of reinforced concrete-filled composite plate shear walls using an optimized computational intelligence model. The proposed model was developed and validated based on 47 laboratory data points and the Transit Search (TS) optimization algorithm. Using 80% of the experimental dataset, the optimized model was selected by determining the unknown coefficients of the network-based computational structure. The remaining 20% of the data was used to evaluate the accuracy of the model, and the best-performing structure was selected. Furthermore, the final neural network details were subjected to statistical analysis to extract a user-friendly formula, making it easier to apply in practice. The proposed ANN model and the proposed user-friendly formula were then compared with the AISC 341-16 and experimental results and demonstrated their efficacy in predicting the flexural behavior of composite shear walls. Overall, the proposed approach provides a more reliable and efficient framework for estimating the flexural behavior of composite shear walls.
