Investigation of Subpanel Size Effect on Behavior Factor of Stiffened Steel Plate Shear Wall

Steel plate shear wall (SPSW) systems have been used in recent years in highly seismic areas to resist lateral loads. In general, a steel plate shear wall system consists of a steel plate wall, boundary columns, horizental floor beams and optional vertical and horizental stiffener plates. Utilizing...
