Abstract:

Steel Plate Shear Wall (SPSW) has been known as one of the effective lateral resisting systems in the steel structures. The classic types of SPSW consist of plate and stiffeners which connected to the surrounding frame, while using its unstiffened type is more common due to its economical aspects. Optimized usage of strength capacity, high ductility and energy dissipation in steel plate during the post buckling phase make the SPSW as an effective type. The separation of steel plate from columns is a useful idea developed in order to reduce column's and foundation's lateral transferred overturning moments; however it may increase the ductility versus the shear strength.This paper discussed an investigation trend on the stiffened and unstiffened girder-supported panels subjected to monotonic in-plan shear and to understand and to avoid plate's edges tearing, the use of two vertical stiffeners at the ends of plate has been investigated.Finite element method for mathematical modeling to use the pushover method has been the main mechanism for simulation the behavior.The most important parameters such as: Frame aspect ratio, plate width to thickness ratio, covering plate area and the dimension of stiffeners in these systems has been investigated.As conclusion, behavior of these types of SPSW were 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
