000021785 520__ $$2eng$$aNowadays One of the advantages of Steel Plate Shear Walls (SPSWs) is the easiness of openings application in infill plate. The openings are sometimes required for passing utilities, architectural purposes, and structural reasons. More energy absorption and high load carrying capacity and post-buckling behavior of steel walls in the nonlinear behavior of this system has been more substantial than other bracing systems. Great stiffness than the bracing systems, the ability to create opening anywhere in the wall, the possibility of building in the factory and installing it in the place in any weather conditions, a 50 percent reduction in the steel consumption in the design of steel moment frames, speeding up the implementation of the designed or retrofitted projects and reducing the cost of the design and retrofitting, especially in retrofitting the concrete structures are the main advantages of that. Different regulations, including the regulation of designing the steel structures of Canada and 450 FEMA have provided some criteria for designing steel plate shear walls. In 2005, the rules governing to designing of special steel shear wall has been added to the regulation of seismic designing of AISC Steel Structures. In this article it has been tried to acquire the similar behavior of the steel shear walls without opening by installing the stiffness in the place and with the appropriate form on the steel shear walls with openings. For this purpose, the verification of the results of the numerical analysis was done with a laboratory model from the researches of Mr. Alavi and Nategh Elahi in 2013. Then, according to the previous studies, seven models with a scale of one to seven, and the ratio of width to thickness 500, that had higher amount of energy absorption, were selected with perforations by 0% , 20% and 35% ratio and the different models of shape and stiffeners location were loaded reciprocally. According to the obtained results from the analysis of the numerical models under the reciprocal dynamic load and the investigation of the obtained pushover charts and the comparison of the seismic parameters such as strength, stiffness, ductility and also energy
