Effect of geometrical variations on the failure mechanisms of perforated steel plate shear Walls—a parametric study towards a new design

As an effective lateral resisting system, a steel plate shear wall (SPSW) should provide adequate ductility and dissipate energy while protecting its boundary elements (BEs). Herein, the failure modes of recently-introduced design for SPSWs (a perforated panel with web-reduced beam section) was investigated. The aim to control mechanism this arrangement by various geometrical modifications. To obtain high-performing design, interaction structural components studied in terms plastic strain distribution, ductility, strength, stiffness. end, finite element prototype populated range parameters. analyses were carried out varying perforation sizes; then, one excelling combination further challenged altering thickness frame aspect ratio. model successfully distinguished between three common provided interesting insight into causality mechanisms. It found that size perforations beam, horizontal could be manipulated desired mechanism. Therein, tensile dominant where band formed across protected vertical BEs their connections. Moreover, outperformed imperforate counterpart hysteresis absorbed (by about 250%) due increased engagement members. Finally, findings summarised some practical recommendations improving proposed arrangement.
