Calculating Dissipated Energy of Ring-Shaped Steel Plate Shear Wall

Abstract

The goal of this study was to compute the dissipated energy of a ring-shaped steel plate shear wall. One of the parameters affecting the behavior of ring-shaped steel plate shear walls is the R_O/W_C ratio. Findings showed that changing the parameter from 2.2 to 3.3 demonstrated a more appropriate hysteretic behavior and a greater amount of dissipated energy, which was due to the increased possibility of lateral torsional buckling at the place where a ring was connected to a link. Compared to the previous parameter R_O/W_C, the parameter R_O/W_I was found to less affect the behavior of the ring-shaped steel plate shear wall. Increasing this parameter with a lesser slope resulted in reduced dissipated energy as well as reduced resistance and stiffness of the steel plate shear wall. This parameter did not have a significant effect on the dissipated energy percentage. The most important factor in designing this parameter was the congruence of this parameter with the previous one. In other words, the congruence of the ring’s width and the connection link width was found to have a determining role in the behavior of the ring-shaped steel plate shear wall. The wall slenderness percentage (R_O/t & W_C/t) had a significant effect on the type of buckling in the steel plate shear wall. This made these parameters have greater effects on the dissipated energy and its percentage.
