strength, durability, and resistance to external forces. Its ease of installation and customization make it an attractive option for construction projects of various sizes and applications.
have gained significant attention in the construction industry due to their exceptional seismic resistance and high ductility. However, the influence of key parameters such as aspect ratio and tie-stud spacing on the cyclic loading behavior of DSPCWs has not been comprehensively investigated. In this study, ABAQUS software is employed to analyze the effects of aspect ratio and tie-stud spacing on the hysteresis response, stiffness and strength degradation, and ductility of DSPCWs subjected to cyclic loading. The analysis is conducted in finite element analysis software ABAQUS CAE of DSPCW models, considering various aspect ratios and tie-stud spacing configurations. The aspect ratio is found to have a significant impact on the hysteresis response, strength degradation, and stiffness deterioration of the walls. Lower aspect ratios tend to promote greater energy dissipation, resulting in enhanced ductility but also increased strength degradation. Similarly, the tie-stud spacing is shown to influence the stiffness and strength degradation, with smaller spacing leading to improved performance.

Double steel plate composite wall consists of two steel plates connected with each other by tie bar and filled with a concrete infill, resulting in a composite section that can withstand a variety of loading conditions. One of the most common types of loading that these walls can face is cyclic loading, which involves the repeated application of loads in opposite directions. Cyclic loading can significantly affect the structural integrity of steel plate composite walls, making it important to understand their behavior under these loading conditions. One of the most primary advantages of using DSPCW is its ability to withstand high loads and stresses. This makes it ideal for use in high-rise buildings, where the weight of the structure and the forces from wind and earthquakes can place significant stress on the building's walls. DSPCW is a highly versatile but durable structural system that offers numerous benefits, including high
