The usage of Steel Shear Wall is converted from an idea into an approved lateral loading resistance system by design codes over the past few years. One of the most recent lateral loading resistance systems is Steel Shear Wall which was accepted by the CSA in 1994 and by AISC in 2005. Composite Steel Plate Shear Wall is a modern lateral loading resistance system which consists of a steel sheet and reinforced concrete walls that are joined by mechanical shear connectors on one or both sides. Having a thinner and lighter wall and easy installation are the most important advantages of this system in comparison to other lateral load systems. The reason that concrete is used is not only it prevents buckling of steel sheets before they yield, also it acts in resistance and stiffness of seismic systems. Usually an opening is used in shear walls because of architectural limitations or executive or even structural problems. These openings have a significant impact on the seismic behavior of the wall.
In this paper the influence of location and also shape of an opening on Composite Steel Plate Shear Walls will be studied. To do so, firstly the accuracy and sufficiency of analysis method are checked by comparing the experimental results for walls. Then samples modeled in the Composite Steel Plate Shear Wall to see its effectiveness on the wall behavior theoretically with Non-linear Static method or Push Over method. The results which are made by analyzing different models in Abaqus indicate that the more the opening location gets close to center of the wall or the more the opening shape approaches circular shape , the better the wall behavior will be.
