چکیده
Retrofitting buildings against lateral load in the shelf life of buildings is always one of the determinative concerns and factors for designers. In addition to the use of systems like moment frames and braces, applying shear walls as one of the main options in designs is raised. This article investigates the effect of dimensions of circular opening on the center of steel shear walls. In the steel shear walls system, circular openings with different shapes and sizes can be used if needed. Steel shear walls act like cantilevered plate girders in which the columns serve as their flanges, the floor beams as their stiffener, and steel sheets as their web. The basis of the idea of shear walls, which has been seriously considered in the last three decades, is the use of a diagonal tensile field in which a steel sheet is created after buckling. In order to investigate the effect of the size of the circular opening on six types of frames with different dimensions, the displacement of the upper level of the frame was investigated. According to these investigations, it was found that the wall stiffness decreases linearly with an increasing circular opening. In general, it can be concluded that the shear panel with or without the circular opening has a better function than the frame without a shear wall.

Abstract
Retrofitting buildings against lateral load in the shelf life of buildings is always one of the determinative concerns and factors for designers. In addition to the use of systems like moment frames and braces, applying shear walls as one of the main options in designs is raised. This article investigates the effect of dimensions of circular opening on the center of steel shear walls. In the steel shear walls system, circular openings with different shapes and sizes can be used if needed. Steel shear walls act like cantilevered plate girders in which the columns serve as their flanges, the floor beams as their stiffener, and steel sheets as their web. The basis of the idea of shear walls, which has been seriously considered in the last three decades, is the use of a diagonal tensile field in which a steel sheet is created after buckling. In order to investigate the effect of the size of the circular opening on six types of frames with different dimensions, the displacement of the upper level of the frame was investigated. According to these investigations, it was found that the wall stiffness decreases linearly with an increasing circular opening. In general, it can be concluded that the shear panel with or without the circular opening has a better function than the frame without a shear wall.
