“…By forming a diagonal tension field in the steel plate, very large stresses are introduced into the surrounding columns demanding an uneconomical section design to avoid buckling. To improve the behavior of the system, researchers suggested an innovative technique in which instead of attaching the steel plate to the main columns it attaches to the secondary columns [8,9,[18][19][20][21][22]. So the large stresses due to the post-buckling diagonal tension field transfer to the secondary columns and the capacity of the main columns remain free to act as a frame member.…”

This paper presents a new configuration of semi-supported steel plate shear wall to increase its efficiency. For this purpose, the infill steel plate is proposed to be trapezoidal shape instead of a rectangular one. In order to find the most efficient inclination angle of lateral sides, a numerical parametric study was conducted. Five different values of inclination angle including 60, 75, 90, 105, and 120 degrees were considered. Furthermore, two thicknesses of 1.75 and 2.00 mm were considered for steel plate. The area of steel plate was the same for all the models. The models were analyzed using finite element software ABAQUS. Both geometric and material nonlinearity have been considered. In order to validate the finite element modeling, the available experimental results were used. According to the results, comparing to the wall with rectangular plate, the inclination angle of 𝟔𝟎 ° increases the ultimate lateral strength and stiffness of the 1.75 mm-thick wall by 46% and 66%, respectively. Furthermore, a simple approximate model is presented to calculate the load-deformation response of the proposed wall using SAP 2000 program. Despite the simplicity of the method, the results were in good agreement with the results of ABAQUS.

“…Steel plate shear walls, consisting of embedded steel plates, vertical edge members (columns), and horizontal edge members (beams), have been adopted as one of the lateral load resisting systems in high-intensity seismic areas for the past 40 years. The excellent performance of steel plate shear walls in improving structural bearing capacity, stiffness, ductility, and energy dissipation capacity led to the widespread application of this system and different academic scholars have conducted experimental studies [1][2][3] and abundant simulation research [4][5][6][7] on steel plate shear walls, which was tremendously applied in engineering practice [8][9][10].…”

Two specimens of low-yield-point steel plate shear walls used for the experimental investigation into different failure modes of the structure were respectively carried out by the horizontal and vertical loading tests in this paper. The results derived from the horizontal loading test for specimen 1 demonstrated that both the infill panel and the frame column were seriously damaged as the loading level increased with continuous and steady strain growth, in which maximum out-of-plane displacement and strain of the infill panel reached 31.8 mm and 11,735 με respectively, whereas the strain of the frame column reached 13,117 με. Moreover, the structural bearing capacity decreased extremely slowly and the specimen still had a high strength when the controlled displacement of the specimen exceeded 3.28 times the yield displacement, which indicated that the ductility of the structure was excellent. The results of a vertical loading experiment for specimen 2 indicated that the maximum deformation of both the infill panel and frame column occurred in the middle-upper part of the members, with a maximum out-of-plane displacement of 95 mm and 70 mm, respectively. The dramatic out-of-plane bulging phenomenon along the width of the infill plate under the vertical load and the seriously torsional deformation of the frame column were observed.

“…It also exhibits excellent strain hardening characteristics when subjected to cyclic loads. With a low yield ratio, the structure that utilizes LYP steel can redistribute the inelastic stress easily and provides a larger plastic zone [16][17][18][19][20][21][22]. Although the research on the properties and application of LYP steel is on the rise, there are extremely few researches focused on its combination with buckling-restrained brace, especially the shaking table test of LYP steel buckling-restrained bracing structure.…”

To investigate the seismic performance of buckling-restrained braces under the earthquake action, the shaking table test with a two-story 1/4 scale model is carried out for the ordinary pure steel frame and the buckling-restrained bracing steel frame with low-yield-point steel as the core plate. The failure modes, dynamic characteristics, acceleration response, interstory drift ratio, strain, shear force, and other mechanical properties of those two comparative structures subjected to different levels of seismic waves are mainly evaluated by the experiment. The test results show that under the action of seismic waves with different intensities, the apparent observations of damage occur in the pure frame structure, while no obvious or serious damage in the steel members of BRB structure is observed. With the increase in loading peak acceleration for the earthquake waves, the natural frequency of both structures gradually decreases and the damping ratio gradually increases. At the end of the test, the stiffness degradation rate of the pure frame structure is 11.2%, while that of the buckling-restrained bracing steel frame structure is only 5.4%. The acceleration response of the buckling-restrained bracing steel frame is smaller than that of the pure steel frame, and the acceleration amplification factor at the second story is larger than that at the first story for both structures. The average interstory drift ratios are, respectively, 1/847 and 1/238 for the pure steel frame under the frequent earthquake and rare earthquake and are 1/3000 and 1/314 for the buckling-restrained bracing steel frame, which reveals that the reduction rate of lateral displacement reaches a maximum of 71.71% after the installation of buckling-restrained brace in the pure steel frame. The strain values at each measuring point of the structural beam and column gradually increase with the increase of the peak seismic acceleration, but the strain values of the pure steel frame are significantly larger than those of the buckling-restrained bracing steel frame, which indicates that the buckling-restrained brace as the first seismic line of defense in the structure can dramatically protect the significant structural members. The maximum shear force at each floor of the structure decreases with the increase in height, and the shear response of the pure frame is apparently higher than that of the buckling-restrained bracing structure.
