Feasibility assessment and torsional control-based design of a negative stiffness-based isolation system for long-span structures under near-fault multi-pulse ground motion

Key Points

• The isolation system improves torsional control and enhances structural stability.
• Key evidence indicates a significant reduction in structural response under near-fault ground motion.
• Analysis of the negative stiffness design shows potential benefits for large buildings.
• Highlights the need for further testing to validate this novel approach in real-world applications.
