Abstract: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 wi… Show more
“…Fig. 2: Configuration of the slotted steel plate shear wall sandwiched between two precast concrete panels [16] As part of the research conducted by Farzin Aminifar et al [17] in 2020, they also investigated the performance of a new, straightforward, and cost-effective system of buckling restrainers shown in Figure 3. To prevent the SPSW system from buckling, two non-welded channels were placed on two faces of the infill plate.…”

“…Fig. 3: Experimental specimens tested by Farzin Aminifar et al [17] Since SPSWs have higher strength, stiffness, and sufficient energy-absorbing capacity than other lateral load-resistant systems, they have attracted the attention of researchers. This paper numerically investigates the influence of the width-to-thickness ratio on the performance of slotted SPSW using the finite element method (FEM).…”
This paper numerically studies the effect of the width-to-thickness ratio of inclined strips on the behavior of a novel slotted steel plate shear wall (SPSW). The slotted SPSW consists of horizontal and vertical boundary elements (BEs) and two inclined-slotted plates (ISPs) connected by high-strength steel bolts. The directions of the slots in each infill plate are opposite. Steel bolts connect the two infill plates through the created holes at the intersection of each inclined slot. This paper numerically examined four slotted steel shear walls with different width-to-thickness ratios of strips. The research showed that when the slotted steel shear walls were put under cycling loading, the inclined steel strips on one side of the wall were placed in tension; however, the strips on the other side undoubtedly were in compression. Additionally, the study showed that when the width-to-thickness ratio of strips was adequately used, the strength, stiffness, and energy absorption capabilities of slotted SPSWs were significantly increased, whereas the out-of-plane displacement was minimized by 40.00 %.
