In the present study, a number of Steel Plate Shear wall (SPSW) models with various infill plates such as perforated and slit infill panels are analyzed and the results are utilized to discuss about behavior of Steel Plate Shear walls with various infill plates. The ABAQUS finite element package is utilized for all Eigen value and incremental nonlinear pushover analyses. Cyclic loading is in compliance with the ATC 24 loading protocol (ATC 1992). To validate modeling, boundary conditions and loading procedures, the experimental results provided by Darren Vian et al. [102, 103] and In-Rak et al. [48, 49] was modeled and analyzed. Investigation of steel plate shear walls made of different... 

Steel plate shear walls (SPSWs) are popular lateral force resisting systems whose practical applications range from high seismic regions to medium and low seismic areas and wind load applications. The factors which make SPSW attractive include its energy dissipation capacity, excellent ductility, constructability, speed of construction compared to concrete shear walls, reduced architectural footprint compared to concrete shear walls, and increased inelastic deformation capacity as compared to braced frames and concrete shear walls.
In this research, characteristics and behavior of un-stiffened perforated SPSWs using non-linear finite elements software has been investigated. In order to... 

After the 1994 Northridge earthquake when investigations show clear results for brittle failure near Beam-Column rigid Connections, research on these connections begun and various theories were suggested for better performance under cyclic loads. One of the appropriate ways is shifting yield beam location from beam-column connection to the beams only. Reducing the capacity of the beam through the beam flange or web far enough from the column, creating special ductile region in the beam. In this thesis, weakening is made by creating an elliptical opening in web beams. If the correct design criteria for this type of connection are suggested, it can satisfy the "weak beam - strong column" and...
