Investigating the Relative Displacement of Ring-Shaped Steel Plate Shear Walls

Abstract

The goal of the present study was to investigate the relative displacement of a ring-shaped steel plate shear wall. To measure the accuracy, efficiency, and validity of the modeling method and analyze the specimens, the present study analyzed the laboratory specimens tested in Natali Egorova’s study (2014), using ABAQUS software. Results indicated that the ring-shaped steel plate shear wall could almost remove the effect of pinching in the hysteresis diagram of a simple ring-shaped steel plate shear wall and provide an acceptable hysteresis behavior. It was found that an increase in thickness, a decrease in the ring’s radius, an increase in the number of rings, and an increase in the ring’s width could increase the strength of the ring-shaped steel plate shear wall. With the increase of thickness, decrease of the ring’s radius, increase of the number of rings, increase of the connecting link’s width, and increase of the ring’s width, the stiffness of the ring-shaped steel plate shear wall also increased. Also, an increase in thickness, a decrease in the width of the connecting link, and an increase in the ring’s width helped increase the percentage of energy dissipated. According to this study, software models had fully gone through loading cycles, while laboratory specimens had stopped in some stages of loading under laboratory conditions.
