Nowadays, the use of corrugated steel shear walls with sinusoidal, triangular, and trapezoidal waveforms, which are a type of corrugated steel wall without the use of stiffeners, is recommended for delaying the premature occurrence of buckling in the plate. The arrangement of corrugated plates in the structural frame alters seismic parameters; therefore, this research focuses on investigating various arrangements of inclined corrugated plates. To achieve this, experimental specimens are first validated under cyclic quasi-static loading using ABAQUS finite element software. Subsequently, the design of four different arrangements of inclined corrugated sheets with three types of trapezoidal, sinusoidal, and triangular waveforms, each with three different thicknesses, is conducted and compared with vertical and horizontal arrangements. Finally, an optimized model is introduced. Based on the obtained results, the triangular waveform demonstrated better seismic performance in terms of energy absorption, initial stiffness, and ultimate strength. As for thickness, increasing the wall thickness improved its seismic behavior. Additionally, the arrangement with the highest energy absorption and ultimate strength was found in the first arrangement; however, its behavior in the cyclic curve was asymmetric. Therefore, by implementing the triangular waveform in arrangement number 1 in a double configuration, this issue has been addressed in the optimized model.
