This study investigates the effect of steel material properties on the structural behavior of steel plate shear walls through nonlinear finite element analysis. Steel plate shear walls initially resist lateral loads through the shear resistance of the infill plate. After buckling occurs, however, additional lateral resistance is developed through the formation of a diagonal tension field. Therefore, the post-buckling behavior of steel plate shear walls can be significantly affected not only by geometric parameters but also by material properties such as yield strength, tensile strength, elongation capacity, and cyclic hardening characteristics. In this study, a finite element model of a steel plate shear wall was established based on existing experimental results, and its validity was verified by comparison with cyclic loading test results. Subsequently, the load-displacement relationship, principal stress distribution, and tension field formation were comparatively analyzed for conventional steel and low-yield-point steel. The analysis results showed that the steel plate shear wall using conventional steel tended to exhibit localized tension field formation after buckling due to its relatively high yield strength, and the stability of the hysteretic behavior varied depending on the geometric conditions. In contrast, when low-yield-point steel was used, plastic deformation was distributed over a wider region of the infill plate owing to its low yield strength and high ductility. As a result, the formation of multiple tension fields was promoted, leading to more stable post-buckling load resistance and hysteretic behavior.
