“…In order to precisely determine the impacts of various opening types, positions, and opening ratios on the system strength, stiffness, ductility, and damping ratio of the SPSWs, various experimental and numerical investigations were carried out [19,32,39,42,[46][47][48][49][50][51] . H. Darvishi et al used numerical analysis to examine how various perforation ratios affected the behavior of the frame and the infill steel plate.…”

Structural buildings such as steel and reinforced concrete frames usually include doors and windows on the front or back facades, interior to the open areas. This; should be arranged to have an excellent correspondence for the location of shear walls, which are counted as essential elements for lateral stability. As a result, these architectural elements across the building assist in creating areas that are relatively less resistant to lateral loads. This review investigates the behavior of steel plate-framed shear walls with openings when subjected to lateral force exposure by thoroughly evaluating the composition of previous studies. To assess the impact of opening size, type, and layout effects on the overall performance of the lateral force-resisting system. There are studies explore on Steel Plate Shear Walls (SPSWs), both with and without openings. This study emphasizes the effect of openings on shear capacity. It investigates the effect of adding openings to steel plate shear walls on stiffness, ductility, damping ratio, and strength of the system. Key findings from the studies show that openings in SPSWs invariably reduce their lateral stiffness and strength. The amount of deduction in the strength of a structure depends on various factors such as the size, shape, and location of the opening. Additionally, the corners of the opening may experience stress concentrations which can cause tearing and reduced ductility. As a result, it disrupts the tension field action, which is the primary mechanism for SPSW energy dissipation. Most studies reviewed only the relatively thin infill plates and particular boundary conditions, which are highly important but have a gap in thick plates. Caution should be exercised when extrapolating due to thicker infill plates or different frame configurations. Considering a broader range of parameters, further research is necessary to establish comprehensive design guidelines for SPSWs with various opening configurations.

“…The test results showed that the interval between the two openings had no effect on the structural parameters. Sabouri-Ghomi et al (2015) conducted experimental investigations on three stiffened SPSWs, each with two rectangular openings and with different separations. FE analysis was also undertaken to validate the theoretical approach using the new plate frame interaction method.…”

“…They assessed the proposed equation by analyzing a series of single-story perforated SPSWs with different aspect ratios and different perforation diameters. Sabouri-Ghomi et al (2015) experimentally studied the structural behavior of stiffened SPSWs with two rectangular openings and with different separations subjected to cyclic loads. Also, they determined the shear stiffness and ultimate shear strength of the SPSWs theoretically through the plate-frame interaction model.…”

Placement of steel plate shear walls (SPSW) in the building cores around the elevators and stairs necessitates door-type openings in these systems. Because of large dimensions of door openings, the energy dissipation capacity drops significantly and thus, the probability of out-of-plane buckling under lateral load increases. Accordingly, introducing stiffeners around the opening increases the amount of dissipated energy and improves the performance of the SPSW system. This paper evaluates the seismic risk of SPSW systems with different arrangements of stiffeners around the door opening. Risk, in this context, denotes the probability of failure times the cost of failure of a given SPSW. The probability of failure is computed through a finite element reliability analysis in which material properties, element geometries, and the lateral force are random variables. The failure event is described by a limit-state function as the exceedance of the drift ratio of the SPSW from a prescribed threshold. The drift ratio is computed by subjecting the finite element model to non-linear static analysis in ABAQUS. The reliability analysis is conducted for a variety of single-story SPSW models having door opening with different arrangements of stiffeners and also for a typical SPSW model without opening as a base model. Next, decision analysis is employed to identify the optimal arrangement, i.e., the one that is associated with the minimum risk. Finally, the effect of risk aversion on the optimal decision is studied by introducing risk-averse utility functions with different degrees of risk aversion.
