“…This structure has been applied in three practical projects in Japan. Subsequently, many scholars have proposed many different forms of steel plate shear walls with openings or slots and low yield point steel plate shear walls [19][20][21][22][23][24], but these protect the columns at the expense of stiffness and bearing capacity of steel plate [25]. In 2013, Clayton et al [26][27][28][29] proposed a self-centering steel plate shear walls.…”

A steel plate shear wall often uses partially encased composite (PEC) columns instead of edge frame columns. Such a steel plate shear wall not only bears the gravity load of the structure and resists the bending moment caused by lateral force by taking advantage of the high bearing capacity and bending stiffness of PEC columns, but also effectively anchors with the frame column to counteract the tension field generated by the steel plate. Therefore, the performance of the steel plate shear wall after buckling can be fully exerted and the seismic performance of the structure can be improved. In order to investigate the seismic performance of the structure, a 1/3-scale specimen test of steel plate shear wall with PEC columns is designed and fabricated, and a finite element model is established with the same size of test. It is found that the test and simulation results are in good agreement, which confirms the reliability of the simulation. Subsequently, 20 models with different parameters of steel plate shear wall with PEC columns are analyzed using ABAQUS. Finally, the failure mode, hysteretic behavior, skeleton curve, and bearing capacity of steel plate shear wall with PEC columns are obtained. The results show that PEC columns have a good anchoring effect on the diagonal tension field and can fully exert the plasticity of the infill steel plate, so that steel plate shear wall with PEC columns has superior seismic performance. Experiments also reveal that the crack type of damages appear in a steel plate shear wall with PEC columns, and, as a future work, the authors will explore the use of structural health monitoring methods, such as piezoceramic transducer-based method, to monitor such cracks.

“…e groove plays an important role in the practical engineering. In the application of civil engineering, Wang et al [1] studied the seismic behavior of self-buckling-restrained steel plate shear wall made by two incline-slotted infill plates, which can avoid the cracks commonly encountered in solid steel filler plates under repeated shear buckling, and inclined steel strips are sequentially generated. Efforts are also made to influence the groove on the processing technology.…”

Carbon-fiber-reinforced polymer (CFRP) has been widely used in aerospace structures for its high strength to weight ratio and high stiffness to weight ratio. However, current pyrotechnic separation devices are mainly made of metal materials, the cutting research on CFRP composites is limited, and the effect of weakening groove on cutting results of composites is unclear under the action of shaped charge jet. In this paper, there firstly established a three-dimensional model of explosive cutting of CFRP composites by nonlinear finite element analysis (FEA), and based on the separation time, delamination, and kinetic energy of the laminate, the influence of weakening grooves on cutting results to the laminate is discussed. The results show that, in contrast to laminates with weakening grooves, laminates without weakening grooves increase the delamination of laminates. At the same time, here, we carried out the explosive cutting test on CFRP composites to verify the rationality of the simulation model. In addition, in order to obtain a better model under the action of shaped charge jet, we optimized the width and height of weakening groove by simulation calculation. Therefore, it proves that this study can guide the application of CFRP composites subjected to shaped charge jet in aerospace separation engineering.

“…In comparison with the free infill panel, the adoption of RS-SPSW results in higher energy dissipation and a more stable hysteretic response. The behavior of selfbuckling-restrained (SBR) SPSW structure has been explored by Wang et al (Wang, Xue, and Xiao 2017). The SBR-SPSW is made up of two inclined-slotted infill plates (ISIPs) which are bonded together by a rubber panel.…”

A novel, simple to apply, and economic buckling restrainer system is introduced for steel plate shear walls. The shear wall panel is restrained by parallel non-welded channel restrainers, which are installed on both sides of the steel panel. A set of experiments were designed to examine improvement in the seismic performance of the shear wall due to the application of the proposed restrainer system. Three 1/4-scale down single-story single-bay steel panel specimens including one panel without and two panels with different number of restainers are subjected to cyclic loading. The behavior of steel panel with and without the restrainers is assessed in terms of initial stiffness, ultimate loading capacity, stiffness/strength degradation, and energy dissipation capacity. The use of the proposed restrainer system significantly improves the energy dissipation capacity of the shear wall and this enhancement is increasing at larger drifts. Employing the proposed restrainer system, there is only a slight increase in the ultimate loading capacity, and at the same time, a significant increase in the initial stiffness of the shear wall. No strength degradation is observed for the range of the drifts up to 5%. A design recommendation for the sizing of the parallel restrainer components is also included.
