“…No research has been conducted till to date on such DSCW system [16][17][18][19][20][21][22][23][24] under in-plane cyclic shear loading. This research by the Authors [25] will make original contributions to the understanding of the hysteretic behaviour of DSCWs with ECC compared to conventional SCC based on strength/stiffness, strength/stiffness degradation, ductility, stress development, and energy absorbing capacity.…”

“…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).

“…Nie et al [4] investigated the seismic behavior of high-strength composite walls composed of concrete filled steel tubular (CFT) columns at the two boundaries and high-strength concrete filled double-steel-plate wall body. Rafiei et al [5] and Hossain et al [6] investigated the behavior of composite shear walls consisting of two skins of profiled steel sheeting and an infill of concrete under in-plane monotonic and cyclic loading respectively, demonstrating more ductile behavior and higher energy absorbing capacity. Chen et al [7] studied the double steel plate-high strength concrete composite walls with concrete filled steel tube boundary elements, showing high strength and excellent deformation capacity.…”

This paper studies the seismic behavior of steel and concrete composite shear walls with embedded steel truss, a crucial structural element for use in high-rise buildings. Three one-fourth scaled composite wall specimens with an aspect ratio of 1.0 were tested until to failure under reversed cyclic lateral load and constant axial load. The test parameters were the amounts of embedded truss chord and web brace. The behavior of the test specimens, including the damage formation, failure mode, hysteretic curve, stiffness and strength degradation, energy dissipation and ductility, were examined. Test results indicated that the embedded truss web braces affect significantly the hysteretic behavior of the composite walls in terms of lateral load capacity, energy dissipation and ductility, while the embedded truss chords can enhance the lateral load capacity. To further broaden the test results obtained, while searching for the optimal design, finite element (FE) models were validated against all the test results. Then 27 FE models that cover the practical ranges of axial load ratio, amount of embedded steel truss chord and web braces were adopted in a parametric analysis to investigate their effects on the wall performance. The results indicate that high axial load ratio is beneficial to initial stiffness and lateral load capacity, while adverse to energy dissipation capacity. Although increasing the volumetric ratio of embedded truss web brace can most effectively increase the lateral load capacity, a medium level about 1.59 % is its optimum value for ensuring the critical seismic performance in terms of energy dissipation and ductility. In order to avoid the adverse effect on ductility behavior, the axial load ratio should be limited to the medium level, about 0.13 for the nominal value or about 0.30 for the design value.
