Evaluation and comparison of behavior of corrugated steel plate shear walls
Latin American Journal of Solids and Structures
In this paper, the nonlinear behaviour of steel plate shear walls with corrugated plates under lateral pushover loading conditions in the models' top level has been analytically investigated by the finite element method. The one-storey frames have beams and columns as boundary elements. Steel plate shear walls are simulated using the finite element method, based on the available experimental models in the literature. After calibration of the analytical models, more parameters of steel shear
... of steel shear walls with corrugated plates, such as the thickness of the corrugated plate, the stiffness of the boundary elements, the corrugation depth in the corrugated plates and the corrugation length of the infill of the corrugated plates, are investigated. The results of this study have demonstrated that in the wall with constant dimensions, the trapezoidal plates have higher energy dissipation, ductility and ultimate bearing than sinusoidal waves, while decreasing the steel material consumption. 764 Y.

In the second type of wall, a belt series or steel profiles are utilized as stiffeners with different arrangements -horizontal, vertical and diagonal -on one side or both sides of the wall until the energy dissipation, stiffness and ultimate bearing are increased. The first method is completely uneconomical because to improve the hysteresis curve of the walls described it is necessary to increase the thickness of the steel plate until the plate does not buckle before yielding; this increase in thickness will be very significant and uneconomical. The second method, which involves strengthening the plate by a series of stiffeners, is economical and quite effective. By using this method, the hysteresis curves turn from an S-shape to a spindle shape and increase the hysteresis curve area. However, this method, primarily due to welding operations, causes weaknesses of the plate within. It also has higher costs for joining the stiffeners to the wall. (Astaneh-Asl, 2001; Behbahanifard, 2003; Berman et al., 2003) . Corrugated steel plates, due to their ductility and low cost, are an appropriate alternative system in these walls. On the other hand, in corrugate plates, the plate's wave function is similar to that of the stiffeners and it has appropriate stiffness too. The performance of steel shear walls is similar to that of the plate girder; as shown in Figure 1 , the plates, columns and beams are the same as its webs, flanges and stiffeners, respectively.
