The direct displacement based-design is a design method that has a simplified procedure to design of structural member and in recent years, has been developed to design of structures by the researchers. This method was first established just for concrete structures and bridges and then has been developed for steel structures such as moment Frames, concentrically and eccentrically braced-frames and Buckling-restrained braced frames. However, steel shear walls have not been studied. The main parameters of the direct displacement based design are the yield displacement and the hysteresis damping where is studied in this paper for steel shear walls. To achieve this purpose, two types of frames with different dimensions and plate thickness (2, 4, 6, 8, and 10 millimeter) are designed based on plate capacity according the AISC 340, and by using plate and frame interaction (PFI). The effective design parameters of steel shear walls are obtained by the hysteresis static analysis and simplified expressions are proposed to the design goals. The results showed that, the yield displacement and the hysteresis damping depended on frame height, plate thickness and material properties.Simplified expression to determine the damping was proposed in terms of the ductility, the plate thickness, and the height of the frame. |
