Resilience (structural engineering) is the capacity of a structural system, or a network of interconnected structures and infrastructure, to withstand, absorb, and recover from the effects of disruptive events, such as natural hazards (e.g., earthquakes, high winds, floods) or man-made threats (e.g., blasts). This concept encompasses the ability to resist initial damage while maintaining a baseline level of function, the capacity for rapid restoration of full functionality or predefined performance levels, and the minimization of downtime, economic losses, and social disruption. It represents a critical performance objective focused on post-event recovery and continuity, evaluated based on characteristics such as robustness, redundancy, resourcefulness, and rapidity, and is distinct from resilience concepts applied in psychological, social, or ecological domains.
