Effect of the girder-supported steel plate on SPSW’s seismic behavior

The conventional type of Steel Plate Shear Wall (SPSW) consists of a steel plate which connected to the surrounding frame. The separation of steel plate from columns is a useful idea developed in order to reduce of column's and foundation's lateral transferred overturning moments. This paper discussed, pushover analyses on the girder-supported panels subjected to monotonic in-plan shear by finite element method. To avoid plate's edges tearing and increase its strength, use of two vertical stiffeners at the ends of plate has been investigated. The most important parameters such as frame aspect ratio, plate width to thickness ratio, covering area of the plate to frame ratio and the dimension of stiffeners in this system have been investigated. As conclusion, behavior of this type of SPSW was comprised with the classic type to find and publish the different aspects, and therefore, appropriate behavior of this system has been studied, specially for rehabilitation and retrofitting the existing buildings and damaged structures
