The Study of Stiffened Steel Shear Walls Pushover Curves

Steel shear walls are used as a lateral load resisting system in structures. One of the most important characteristics of this system known as high energy absorption capacity, remarkable stiffness, strength, and ductility. For practical design purposes, the knowledge of the general behavior of steel shear walls is needed. This empirical data could be obtained by conducting experimental and theoritical works. In this study the tests conducted on stiffened steel shear walls were considered. Samples tested in the laboratory were modeled using ANSYS program and obtained results including pushover were compared with empirical data. In addition pushover curves for laboratory data were compared with those obtained by Plate Frame Intraction (PFI) method of Sabouri-Roberts. A good correspondence is observed. Furthermore, in this study the idea of using EGS in steel shear walls was tested. It was seen that using EGS system with yielding point 100N/mm2 that is about 2.5 times less than yielding point of steel which was used in the tests, corresponding displacement with yielding point decreases in the same ratio.
