To improve buckling stability and to prevent early elastic buckling of infill plates, vertical and horizontal plate stiffeners are designed for steel plate shear wall (SPSW) systems. Furthermore, effective design of stiffeners for SPSW systems results in improved structural behavior, such as increase of stiffness, capacity and energy absorption. In this paper, the effect of stiffeners is studied on SPSW structural behavior and consequently a rational method is proposed to determine the minimum required moment of inertia for stiffeners resulting in local buckling mode of the infill plate. The proposed requirement is then compared to results obtained from tests previously conducted, as well as those gained from finite element (FE) analyses performed for this study.

Steel plate shear wall (SPSW) is commonly used in civil schemes because of its good deformability and stiffness. In this research, the numerical analysis of steel plate shear wall (SPSW) with unstiffened infill steel plate is conducted. This paper explains the effect of thickness variation of infill steel plate on behavior of steel plate. In this status, several samples are designed and checked by rigid frame and actuator. The experimental samples is joined to a rigid frame. 3 numerical specimens consist of steel plate shear wall with different thickness (1.5, 3, 4. 5) mm formed by finite element code which is advanced by the Amirkabir university. To confirm the model, numerical results were discussed with a valid experiment which explain suitable agreement. Numerical model tested under cyclic loading with frequency of 1/60 Hz. Results show that the increase of infill steel plate thickness enhance stiffness and ductility ratio of model. And so, would decrease energy absorption in comparison with the reference model.

Fiber Reinforced Polymer (FRP) strengthening of structures has been gaining increasing interest, traditionally in application with concrete structures, and more recently in application with
steel structures. Because of their unique blend of properties, composites reinforced with high performance fibers find use in many structural applications. This paper defines the effect of FRP layers on behaviour of steel plate. In this regard, some models are selected and tested by rigid frame
and actuator. The experimental model is connected to a rigid frame.
The FRP layer acts similar to a lateral support for the steel plate, and possesses the intelligent behavior (specified control for establishing of flexural line and further leaning towards post buckling condition), meaning that the FRP layer can lead the local flexural deflection towards the total flexure
of the steel plate and effectively contributes more in resisting the shear stresses and extension of post flexure lines in steel plate and formation of composite plate. This is due to involvement of more area of steel plate to resisting of the imposed stresses. Result shows, the FRP layers would increase the stiffness, energy absorption, shear capacity and will be decreasing the ductility of steel plate as compared with composited steel plate with other materials as reinforcement concrete.

In this study, the behavior of perforated carbon fiber reinforced polymer–steel composite shear walls under a quasi-static cyclic loading was investigated. Four single-story and single-bay specimens were manufactured with an aspect ratio of 1.33: a simple perforated steel shear wall as a reference model and three perforated composite shear walls. The composite specimens differed in their fiber directions. All specimens had a regular staggered pattern of circular openings. Parametric studies on the stiffness, load-carrying capacity, and ductility were carried out using hysteresis curves. As a detailed new study the strain on the infill panel and buckling waves were also monitored. All the fiber directions were found to considerably affect the stress distribution and tension field direction. While, hysteresis curves indicated that orienting the fibers along the tension field considerably affected the curves and the above parameters, but the effect of fiber orientations in the horizontal and vertical was negligible.

This paper describes a 2-story steel plate shear wall frame (SPSWF) specimen tested recently by using sub-structural pseudo dynamic testing procedures in National Center for Research on Earthquake Engineering. The paper focuses on the design procedures, experimental setup and phase I test results. The thickness of SS400 grade steel plate for first story wall is 3mm; and for the second story is 2mm. All the boundary beam and column elements are A572 GR 50 steel. In phase I test, the SPSW in each story has horizontal tube restrainers on both sides to minimize the out-of-plane displacements and the buckling sounds. The specimen was tested under pseudo-dynamic loads using three ground accelerations, which were recorded in the 1999 Chi-Chi earthquake and scaled up to represent seismic hazards of 2%, 10%, and 50 % probabilities of exceedance in 50 years. Test results show that 1) the SPSWF specimen sustained three earthquakes without any significant wall fracture or overall strength degra...

During the past few decades, steel plate shear wall (SPSW) has been used as a lateral bearing system in building construction; however, the wall boundary conditions have been considered symmetric and identical in most of the performed projects and researches. In this paper, the system response modification factor is numerically investigated in the condition that the boundary components are dissimilar. These wall models could be seen when architectural and facility limitations are governing in the design or in the seismic retrofitting of existing structures, when boundary components especially the columns are of non-identical dimensions. Moreover, the necessity of this investigation would be important concerning the role of response modification factor in seismic design of structures. In the present study, three-story single-span SPSW models were built by using finite element method, in which the boundary components were different from each other in the moment of inertia and the results were then taken into comparison. The Response modification factor of steel plate shear wall (SPSW) in condition of identical and non-identical boundary elements has been calculated through Uang approach and Newmark & Hall method. The same investigation on ductility, energy absorption and ultimate strength has been accomplished as well.

In this paper, the effectiveness of the Modified Plate–Frame Interaction (M-PFI) model is evaluated by comparing its outcomes against those from experimental results obtained from a number of steel plate walls (SPWs) tested at different universities. As a result of the comparison, the M-PFI model was found to provide satisfactory predictions for SPW specimens constructed with steel plates welded to column and beam members. The M-PFI model was able to predict the initial stiffness, as well as to evaluate whether the boundary members of the SPW have sufficient capacity to allow for the infill plate to yield entirely. However, the model was found to underestimate the ultimate capacity of the SPW system mainly because, among other reasons, the material model used for its underlying theory is the elastic – perfectly plastic material model.
