Steel Shear Walls are a lateral resistance system in frames that has attracted many researchers’ attention owing to advantages such as appropriate ductility, high stiffness, significant shear strength and energy absorption. Since the early 1980s, when key researches on unstiffened Steel Shear Wall (SPSW) were under considerations, researchers were continously trying to improve the performance and efficiency of this system. One of these efforts was the creation of the opening in infill plate. Studies on perforated-SPSW began in the early 1990s by the experiments of Sabouri and Roberts. Recently a perforated-SPSW which having some circular openings was presented and examined by the researchers of Buffalo University. In addition to a system for passing the utility through the infill plate, this kind of opening is useful when a required thinner plate is not available, so it can be possible to substitute a proper multi-perforated Steel Shear Wall with a solid plate. This paper presents results of a research on the effect of multi openings on the performance of SPSW. Beside the experimental investigation a numerical study was conducted using the well-known ABAQUS finite element program was conduvted. Eventually the results of numerical and experimental studies were compared with the Plastic analysis’ conclusion. Results show a good agreement between experimental and numerical hysteresis and envelop curves. Furthermore, the Plastic analysis reduction factors seem to be conservative.
