“…(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.

“…e pseudo-static (low-cycle reciprocating horizontal loading) test showed that the shear wall retained good ductility at a high axial compression ratio (0.7). In addition, Hossain et al [19,20] and Rafiei et al [21,22] experimentally examined the performance of steel plate-concrete composite shear wall with a pair of tensile connectors under the action of reciprocating hysteresis and unidirectional push-over loads. e results showed that the presence of tensile connectors further improved the ductility and energy consumption capacity of the component and prevented premature buckling of the profiled steel plate.…”

In this study, the mechanical performance of multicavity concrete-filled steel tube (CFST) shear wall under axial compressive loading is investigated through experimental, numerical, and theoretical methodologies. Further, ultrasonic testing is used to assess the accumulated damage in the core concrete. Two specimens are designed for axial compression test to study the effect of concrete strength and steel ratio on the mechanical behavior of multicavity CFST shear wall. Furthermore, a three-dimensional (3D) finite element model is established for parametric studies to probe into compound effect between multicavity steel tube and core concrete. Based on finite element simulation and limit equilibrium theory, a practical formula is proposed for calculating the axial compressive bearing capacity of the multicavity CFST shear wall, and the corresponding calculation results are found to be in good agreement with the experimental results. This indicates that the proposed formula can serve as a useful reference for engineering applications. In addition, the ultrasonic testing results revealed that the damage process of core concrete under axial load can be divided into three stages: extension of initial cracks (elastic stage), compaction due to hooping effect (elastic-plastic stage), and overall failure of the concrete (failure stage).

“…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. Many experimental results and numerical analysis indicated that the composite shear walls have advantages in the mechanical properties by combining the effect of two types of materials and practical significance in bearing shear force .…”

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...
