Abstract: Ring shaped - steel plate shear walls (RS-SPSWs) are a newly invented lateral load resisting system. It resists the buckling of the panel through the deformation properties of the rings. This paper is an attempt to develop a new RS-SPSW that has more strength, stiffness and energy dissipation. The configuration of cut-outs, thickness of steel plate, outer radius of the rings, width of the rings etc are selected as the input parameters for this study. In order to simulate the behaviour of RS-SPSW, a non linear static analysis was conducted by using ANSYS 14.5. Hysteretic curves, monotonic load displacement curves and out of plane displacement of plate are demonstrated. From the preliminary analysis of RS-SPSWs under different configuration of alignment of the rings, it is found that the steel plate shear wall panel with rings arranged along perimeter (RS-G-3) as well as completely aligned ring models (RS-G-2) shows promising results. While comparing RS-G-2 and RS-G-3, RS-G-3 has strength and stiffness about 10.82% and 48.11% than that of RS-G-2. Increase in plate thickness and width of the connecting ring as well as decrease in outer ring radius shows improvement in efficiency of both structures. Based on the different parametric analysis, it can be concluded that RS-G-3 shows better performance on the basis strength and stiffness. Conversely RS-G-2 shows more energy dissipation than that of RS-G-3.
