Abstract
Unstiffened steel plate shear walls have low buckling strength, which caused development diagonal tension field under lateral load. Corrugated plates have higher out-of-plane stiffness and improved buckling stability. Combining corrugated and flat plates in steel shear wall web could be effective. In this paper a new steel shear wall system reinforced with trapezoidal corrugated steel plates were proposed. In this study, the behavior of the system was experimentally studied under cyclic loading. Four specimens with the one-third scale were evaluated, which were control unstiffened specimen, the specimen with vertical 45° trapezoidal corrugated web, specimen with a corrugated web plate reinforced with two flat plates, and specimen with a flat web plate reinforced with two corrugated plates. In all four specimens, the total thicknesses of steel plates were the same; therefore, the thickness of each plate in specimens with three plates was one-third of the specimen with one plate. The studied parameters were the bearing capacity, maximum base shear, stiffness, ductility, energy absorption, and modification factor for the dissipation capacity of the specimens. The results revealed the maximum lateral load capacity of specimen with a flat web plate reinforced with two corrugated plates increased about 17%, 37%, and 19%, comparly to unstiffened specimens, vertical 45° trapezoidal corrugated web, and corrugated web plate reinforced with two flat plates, respectively. According to the results, the behavior of the seismic parameters of the proposed specimen with a flat web plate reinforced with two corrugated plates was clearly better than that of the other specimens.
期刊介绍：
Periodica Polytechnica Civil Engineering is a peer reviewed scientific journal published by the Faculty of Civil Engineering of the Budapest University of Technology and Economics. It was founded in 1957. Publication frequency: quarterly.
Periodica Polytechnica Civil Engineering publishes both research and application oriented papers, in the area of civil engineering.
The main scope of the journal is to publish original research articles in the wide field of civil engineering, including geodesy and surveying, construction materials and engineering geology, photogrammetry and geoinformatics, geotechnics, structural engineering, architectural engineering, structural mechanics, highway and railway engineering, hydraulic and water resources engineering, sanitary and environmental engineering, engineering optimisation and history of civil engineering. The journal is abstracted by several international databases, see the main page.
