Steel shear walls have been utilized as lateral load-bearing systems in structures since 1970. The basic idea of this system is to use the diagonal tensile field in which a steel sheet is created after buckling. A comprehensive research on irregularly patterned corrugated shear walls has not been performed so far. In this research, the study of this type of walls and also comparing their performance with flat and corrugated walls with a regular pattern is desired. The comprehensive studies have not been conducted to provide a more irregular and resistant pattern that can improve the seismic properties of regular patterns. This research aimed to present a new model of steel shear wall with irregular wave pattern that can present more buckling resistance than walls with regular wave and also has better performance in lateral control of the structure with ductility and better energy dissipation. For this purpose, the modeling results of finite element software using ABAQUS were compared with a valid laboratory results to verify its accuracy. There was an adequate convergence between the results, which indicates the correctness of the modeling. Then the models were created and dynamic analysis of time history in this software was performed on the models. Analysis of the models indicated that irregular waves can also behave well. In general, it was not possible to comment on the displacement, but there was a certainty about the base cut that the irregularity reduced the base cut to some extent, but still it was not possible to choose a suitable pattern for the irregularity.
