چکیده

Steel plate shear walls consist of thin infill steel plates attached to beams, called (horizontal boundary elements, HBEs),and columns (vertical boundary elements, VBEs) in structural steel frames. The thin unstiffened web plates are expectedto buckle in shear at low load levels and develop tension field action, providing ductility and energy dissipation throughtension yielding of the web plate. HBEs are designed for stiffness and strength requirements and are expected to anchorthe tension field formation in the web plates. VBEs are designed for yielding of web plates and plastic hinge formation atthe ends of the HBEs. This design approach may result in very large demand on boundary frame members, especiallyVBEs in most cases. Several methods such as using LYP, perforating the infill plate and omitting connection of infillplate to columns have been proposed to reduce the moment and axial force demands on the VBEs. The main purpose ofthis research is to study the behavior of steel plate shear walls with various connection of infill plate to columns in multispan moment frames. A numerical study has been performed in order to investigate the behavior of such a system. Theresults of proposed system were compared with those of the conventional SPSWs. Results show that reducing the infillplate connection to columns will reduce the axial forces in columns.
