  7. Abstract:
  8. In this thesis different steel plate shear walls have been investigated using ABAQUS software. These investigations have been focused on various topics, including both boundary frame elements and also the in-fill plate. The main results have been gathered by utilizing different steel plate thicknesses and different boundary frame elements. In order to achieve a better understanding of the effects of both of these elements, various aspect ratios have also been investigated. Moment of inertia has been noted as the main property of both beams and columns used in SPSW. Comparison of the gained results is noteworthy. They show a variety of changes in the load-displacement diagrams, due to changes made in thicknesses and yield stresses of in-fill plates. For instance, it was observed that effects of changing plate's yield stress showed dramatic reduction in smaller thicknesses than thicker plates in most of investigated parameters. Also as aspect ratios grow, the influence of changing plate thickness become more noticeable. Increasing both yield stress and thickness of in-fill plates caused reduction in frames' final capacity. There are much more results available in this thesis and extensive studies have been made on the reasons for each of the observed differentiations in diagrams. Using these diagrams, ductility of all models, in addition to initial stiffnesses and ultimate lateral strengths, have also been attained and put into comparison. In overall, results made in this thesis are mainly useful to get a better understanding of the behavior of this specific lateral load resisting structure
