The use of steel structures in seismic -prone areas is a well-established effective approach due to their strength and ductility, which enables them to withstand the forces generated during earthquakes. Steel shear walls, in particular, are considered one of the best options for seismic resistance. However, recent advancements in steel production have introduced a new material called Low-Yield Point Steel (LYP Steel), Characterised by extremely low yield strength and high elongation properties. This new steel material has the potential to offer unique benefits in seismic design. In the current study, we delve into the seismic performance of a wide spectrum of low yield point steel plate shear walls, encompassing various stiffness configurations and perforation types, including square, circular, and elliptical. The research accounts for shear walls that are unstiffened, horizontally and vertically stiffened, diagonally stiffened, and combinations thereof. Additionally, the impact of varying perforation sizes is considered. This comprehensive investigation seeks to shed light on the diverse structural behaviours exhibited by these shear wall configurations when subjected to seismic forces. The outcomes aim to provide valuable insights into optimizing the use of low yield point steel plate shear walls, guiding engineers and architects in the pursuit of resilient and efficient building designs that meet the evolving demands of seismic-prone regions.
