“…Because of this vital issue, SPSWs aren't widely used. Researchers have proposed several strategies to alleviate the substantial demand for VBE (vertical boundary element) caused by diagonal tension in web plates, including light-gauge SPSWs [15,16], low yield point SPSWs [17][18][19], SPSWs with slit by [6,20], SPSWs with a partially connected web plate to columns [21,22], and self-centering steel plate shear wall with infill web-strips and solid web plates by [23], SPSWs with the considerable disconnected length of web plate to vertical boundary columns and SPSWs with peripheral circular holes [24][25][26][27][28][29]. Other studies [30,31], meanwhile, have adopted SPSWs with partial length connection and largely disconnected to vertical boundary elements.…”

Steel plate shear walls (SPSWs) offer good energy dissipation capability when subjected to seismic forces as a robust lateral load resisting structure. This research investigated the cyclic behaviors of innovative infill web-strips (IWS-SPSW) and conventional unstiffened steel plate shear (USPSW) experimentally and numerically. As a result, two specimens of a 1:3 scale three-story single-bay IWS-SPSW and USPSW were fabricated and tested under cyclic lateral loading. Rigid moment-resistant connections were used for the steel plate shear wall beam-column connection. The steel shear walls with infill web strips showed high ductility and less shear load-bearing than the USPSW. The hysteresis results showed that the IWS-SPSW had high energy dissipation with no severe beam-columns damages. On the other hand, the USPSW displayed severe post-buckling, infill panel cracks, and first-floor column damages. Moreover, the IWS-SPSW shear strength did not fall in the test specimen beyond 2.5% average story drift, where the structure exhibited great seismic behavior. FE models were created and validated with experimental data. It has been proven that the infill web-strips can affect an SPSW system’s high performance and overall energy dissipation. From a parametric study, the material features of the infill web-strips, such as steel strength and thickness, can enhance the system’s impact even more.

“…The LYP SPSW structural system consists of an infill panel made of low-yield-point steel and an external frame [22,23], which possesses the lower yielding characteristic and higher buckling capacity of the infill panel, and prominent lateral resisting stiffness and excellent ductility performance of an overall system [24][25][26]. The low-yield-point steel appears to have extremely low-yield strength, which could dissipate the abundant seismic energy by plastic deformation earlier under the action of an earthquake [27][28][29][30][31].…”

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.

“…The SPSW with LYS infill plate exhibits good shear strength, great deformation, high energy dissipation capacity, and high displacement ductility. Bahrebar et al [ 17 ] investigated the seismic performance of unstiffened, corrugated, and LYP steel walls under monotonic and cyclic loadings. They demonstrated that the use of LYP steel infill plate reduces the strength demand for boundary frame members, and LYP steel enables the establishment of relatively thick web plates with improved buckling and serviceability characteristics.…”

Summary As a new type of lateral load‐resisting system in SPSW systems, corrugated SPSWs (CSPSWs) have been gradually researched and applied. Corrugated plates offer various advantages over flat plates including higher energy dissipation capacity, ductility, out‐of‐plane stiffness, and improved buckling stability. For seismic control and isolation techniques, low yield point (LYP) steels (LY100, LY160, and LY225) are the reliable and ideal energy‐dissipating materials. The low yield point CSPSWs combine high energy‐consuming materials with high‐performance structures to provide a better solution for ductile and seismic resistance of high‐rise and super tall buildings. Currently, there are no design codes addressing the seismic performance of LYP corrugated steel plate shear walls (CSPSWs). This study investigates cyclic behavior and energy dissipation performance of corrugated steel plate yield point (100, 160, 225, 235, and 345 MPa) of different thickness CSPSWs and determine the plate yield point that provides the optimum performance. Results and findings of this study reveal that compared with the ordinary yield strength corrugated steel plates, the low yield point CSPSWs have a larger safety factor of lateral bearing capacity, a fuller hysteresis curve, a strong energy dissipation coefficient, a larger ductility coefficient and a smaller fluctuation range of strength degradation coefficient, and better strength stability. The initial equivalent stiffness of CSPSWs with different yield strengths is the same.
