Steel plate shear walls have emerged as a promising lateral load-resisting system in tall buildings, owing to their high lateral resistance, ductility, and cost-effectiveness. However, they encounter challenges such as imposing significant stresses on surrounding elements and lacking versatility in accommodating different uses. To address these issues, researchers have proposed various solutions, including stiffened steel plate shear walls and shear walls with different types of openings. In this paper, a new lateral resisting system, the steel grid shear wall (SGSW), has been introduced to overcome these limitations. Also this paper presents an experimental and nu- merical investigation of a novel SGSW under quasi-static loading. A SGSW specimen was tested, demonstrating desirable yielding and failure processes. Furthermore, the finite element model of SGSW was validated against experimental results, exhibiting high accuracy. The SGSW specimen displayed stable hysteretic behavior, high ductility, substantial shear strength, and energy dissipation capacity. Moreover, it showed a higher initial stiffness and ductility reduction factor compared to an equivalent steel plate shear wall. The proposed SGSW system presents a viable alternative for lateral load resistance in buildings, offering advantages such as ease of implementation, cost-effectiveness, and stable hysteretic performance.
