Effect of opening location in the wall with corrugated steel plate using the pushover analysis

Steel shear walls are far cleaner and are considered more rapid replacements for the concrete shear walls in terms of execution and more reliable in terms of strength and behavior.  Also the system takes advantage of all good characteristics of concentrically braced frames (CBF) like V and X-shaped bracings, etc. and also those of eccentrically braced frames (EBF). They are also efficient in terms of execution and good behavior and in many cases act better. In this research the effect of opening location in the corrugated plate is investigated using the pushover analysis. For the analysis and investigation of the model, use has been made of ABAQUS software and the two available methods for analysis and design of steel shear walls are incorporated. The obtained results showed that the opening in the corrugated steel shear wall causes reduced safety and lateral resistance of the wall, so that where the openings are located at the corners, the effect of reduction is more severe. On this basis, the minimum reduction in stiffness and strength of the steel shear wall with opening is where it is located at the middle of the wall and the worst case is where the opening is located at the corners and close to the columns.
