TL;DR: In this paper, four scaled one-storey single-bay steel plate shear wall (SPSW) specimens with unstiffened panels were tested to determine their behaviour under cyclic loadings.
Abstract: Four scaled one-storey single-bay steel plate shear wall (SPSW) specimens with unstiffened panels were tested to determine their behaviour under cyclic loadings. The shear walls had moment-resisting beam-to-column connections. Four different vertical loads, i.e., 300 kN, 600 kN, 900 kN, and 1200 kN, representing the gravity load of the upper storeys were applied at the top of the boundary columns through a force distribution beam. A horizontal cyclic load was then applied at the top of the specimens. The specimen behaviour, envelope curves, axial stress distribution of the infill steel plate, and shear capacity were analyzed. The axial stress distribution and envelope curves were compared with the values predicted using an analytical model available in the literature.

Abstract: In this study, in a novel buckling-restrained steel plate shear wall (BRSPSW) with out-of-plane deformation spaces, angle steel stiffeners have been installed so as to create gaps between the steel plate and the covering concrete slabs. A finite element model has been developed to analyse the effect of the gap. According to the finite element results, seismic performance of this novel BRSPSW has been tested under cyclic loading at the scale ratio of 1/3. The failure pattern, hysteretic characteristics, skeleton curve, equivalent stiffness, ductility, and energy dissipation have all been systematically analysed. A stiffened steel plate shear wall (SPSW) has also been tested in order to determine the differences between these two steel shear walls in load-carrying capability and the function and significance of the gap. The test results show that the novel BRSPSW does not only significantly enhance the ultimate bearing capacity, stiffness, ductility, and accumulated energy dissipation of the SPSW but also keep the steel plate basically intact at the end of the test. This can be attributed to the existence of the gaps between the infilled steel plate and the covering concrete slabs. The hysteretic characteristics and the strength and deformation characteristics of this novel BRSPSW have been simulated by using the finite element model, and the test results are in good agreement with the finite element results. Hence, the BRSPSW is an excellent steel plate shear wall to be used in high rise structure to resist horizontal loadings.

Abstract: Corrugated Steel Shear Wall (CSSW) is an efficient shear wall system, which has higher energy dissipation capacity, ductility and stiffness when compared to the Steel Plate Shear Wall (SPSW) with flat infill plate. Despite of these advantages, the ultimate load of CSSW is lower than that of SPSW. Various studies conducted to improve the cyclic behavior of CSSW revealed that increasing corrugation angle might enhance energy dissipation capacity and toughness of CSSWs. However, the ultimate load of CSSW was not improved by increasing the corrugation angle. Thus, the current study proposed new corrugated infill panel schemes to improve the ultimate load of CSSWs. To this end, Finite Element (FE) models were established using ABAQUS/Standard and verified with the experimental results from previous researches. The corrugation angle of the proposed plates was found based on a numerical investigation on seven CSSW FE models with the corrugation angle ranges from 30° to 120°. The FE results revealed that the model with the corrugation angle of 120 achieved highest ultimate load, energy dissipation capacity and toughness amongst the CSSW models. In addition, the ultimate loads, energy dissipation capacities and toughness of the proposed infill plates were up to 11.8%, 53.9% and 8.8% respectively higher than those of CSSW model with the corrugation angle of 120°. Furthermore, the proposed infill plates use up to 13.4% lower amount of steel compared to the corrugated plate with the corrugation angle of 120. Doi: 10.28991/cej-2021-03091678 Full Text: PDF

TL;DR: In this paper, a steel plate wall is composed of a steel frame with a thin infill plate welded inside of it, which dissipates energy through yielding of the infill plates in the form of a diago-nal tension field.
Abstract: RESUME Le mur de refend ductile en acier est un systeme de reprise des charges laterales tres performant pour les bâtiments multi etages. Sa ductilite, sa rigidite et la redondance qu’il offre en font un systeme de choix pour la resistance aux charges sismiques. Le mur de refend est constitue d’un cadre en acier dans lequel est inseree une plaque elancee qui dissipe de l’energie par la formation de champs de tension. Pouvant etre en grande partie prefabrique en usine, son utilisation peut egalement permettre de reduire les delais d’erection au chantier. Malheureusement, les couts de fabrication eleves empechent souvent son utilisation dans les bâtiments au Canada. De plus, pour les bâtiments plus hauts, les dimensions du mur doivent etre augmentees et la prefabrication en usine et la livraison deviennent plus difficiles.----------ABSTRACT Ductile steel plate walls are a very efficient lateral force resisting system in multi-story buildings. Its high ductility, stiffness and redundancy make it an ideal choice for resisting seismic loads. A steel plate wall is composed of a steel frame with a thin infill plate welded inside of it. During a severe earthquake, energy is dissipated through yielding of the infill plate in the form of a diago-nal tension field. Erection time on the work site can be greatly reduced by pre-assembling the wall in the shop before sending it out. However, the high fabrication costs often preclude from using the system in buildings in Canada. Additionally, for taller buildings, wider walls are re-quired, which cannot be preassembled in the shop and shipped to the site.
