Abstract

Steel plate shear wall (SPSW) is considered a suitable lateral load-resisting system in new and retrofit structures. This system is nevertheless plagued with a plethora of challenges. One of its major drawbacks is the need to use sheets with very low thickness given the required force in the design, which, in addition to the complications in installation, does not provide the minimum dimension needed for welding. In this research, the laboratory samples tested by Egrova et al. (2014) were modeled and analyzed in Abaqus to measure the accuracy and efficiency of the proposed model. The results showed that the change in the parameters of ring-shaped steel plate shear walls (RS-SPSW) has almost the same effect on the strength and stiffness of the wall. As such, evidence suggests that it is difficult to design the wall by altering the parameters of ringshaped steel plate shear walls, separately and with a different purpose in terms of stiffness and strength. Nevertheless, changing the number of rings in a frame more effectively provides the capacity to have a design with different stiffness and strength. The strength of RS-SPSWs can simply be improved by increasing the thickness, decreasing the ring radius, increasing the number of rings, and increasing the ring width. Moreover, the strength of RS-SPSWs can be optimized by increasing the thickness, reducing the width of the connecting link, and increasing the width of the ring. Ultimately, increasing the thickness, decreasing the width of the connecting link, and increasing the ring width heightens the rate of energy dissipation.
