“…e diagonal tension strips exert substantial axial and flexural demands on columns, leading to a condition that makes columns susceptible to premature failure. To decrease column demands in SPSWs, researchers have come up with a number of methods such as offsetting infill plates on each story [1], using an outrigger system in SPSW structures [19,20], using coupling beams to link two SPSWs together [21], perforating infill plates to decrease SPSW stiffness and strength [22], applying low-yield point steel to infill plates [23], using a pin-ended horizontal strut at the midheight of columns on every story [24], utilizing reduced beam sections for the beam-to-column connections [25,26], using a lightgauge plate for infill plate [8], introducing secondary columns as new boundary elements [27], and releasing infill plates from columns and connecting them to the beams only [28][29][30][31][32][33]. e latter option is of interest in this study.…”

Lately, Corrugated Steel Plate Shear Walls (CSPSWs) have gained significance and reputation for being effective lateral force-resisting systems. Corrugated plates are characterized by greater out-of-plane stiffness and buckling stability than flat plates, ensuring their enhanced hysteretic behavior. In ordinary Steel Plate Shear Walls (SPSWs), infill plates are fixed to beams and columns. But, detaching the infill plate from columns and connecting it to the beams only is assumed here as a method for reducing column demands. The current study explores the cyclic performance of CSPSWs with beam-only-connected infill plates. The design of a one-story single-bay specimen was done and its finite element model was developed. Parametric studies have targeted CSPSWs with different geometric variables, including orientation, thickness, and aspect ratio of the infill plate. Noteworthy responses were ultimate strength, initial stiffness, energy dissipation capacity, and force-deformation relationship. The obtained results indicated that selecting the right geometrical parameters could yield a desirable cyclic performance. Finally, an analytical method was proposed for calculating the ultimate shear strength of beam-only-connected CSPSWs.

“…The material for infill plate and boundary frame components were ST12 and ST37 steels according to DIN standard [19], respectively. Mechanical properties of ST12 and ST37 steel were adopted from coupon tests done by Hosseinzadeh et al [20] and Jahanpour et al [21], respectively and are shown in Table 1. In order to get cyclic deteriorations in the steel material strength and stiffness, "ductile damage" using stress triaxiality dependent fracture initiation criterion and fracture evolution law in the form of strain softening was accommodated in material modelling [22].…”

Recently, corrugated steel plate shear walls have been shown to be an efficient lateral force resisting system for building structures. Corrugated plates have higher out-of-plane stiffness and improved buckling stability in comparison with flat plates which result in improved hysteretic behavior. However, the thickness of the corrugated plates may be limited due to the cold-form process restrictions. This paper investigates the cyclic performance of double corrugated steel plate shear walls. One-story single-bay specimen was designed and modelled and parametric studies were performed. The parametric study considered the orientation of corrugated plates (horizontal or vertical), disconnection of infill plates from columns, disconnection of infill plates from each other, infill plate thickness and infill plate aspect ratio on cyclic performance of double corrugated steel plate shear walls. The present study results show that proper selection of the aforementioned parameters can lead to a desirable cyclic performance. In the end, a recommendation for calculating initial stiffness and ultimate strength of double corrugated steel plate shear walls is given.

“…In order to fully utilize the capacity of the plate, a diagonal tension field action must be uniformly formed in it. Achieving such a goal requires that the boundary elements, especially the columns, must have a very high bending stiffness [3,4]. The use of very strong columns in terms of bending stiffness makes the design look uneconomical and heavy.…”

In the recent five decades, steel shear walls have been one of the most important systems in the construction and rehabilitation of many structures. The system has many advantages including high strength and stiffness, high ductility and excellent energy dissipation capacity. Steel shear walls are made and executed in different types. These include walls with and without stiffeners as well as composites. Recent research shows that they are a type of steel shear wall in which the infill plate is slightly away from the boundary members. In fact, there is no connection between the infill plate and one of boundary members. Therefore, in this study, the behavior of traditional one-story-one-span steel shear walls with 4 different lengths was investigated. For comparison, walls in which the sheet was attached only to a beam or column were examined. Obtained results from the study showed that the lateral bearing capacity of samples with free beam or free column is less than that of samples with full connection, on average 20%. Also, the strength of the samples with free column is slightly higher than the samples with free beam. In addition, boundary members, especially columns, are much less affected by forces in free-column specimens than in other specimens, and this could decreases economical costs.
