Performance-Based Framework for Quantifying Structural Resilience to Blast-Induced Damage

AbstractThis paper proposes a decision-based framework to quantitatively define an indicator of structural resilience, as it pertains to mitigating blast-induced damage. The proposed procedure starts with the characterization of hazards and calculates the associated damage propagation and functional losses by deriving and subsequently balancing functional relationships between load, design, and consequences. The outcomes of each step are articulated through a series of generalized variables: (1) topology, (2) geometry, and (3) damage. Current performance-based methodologies are reviewed and adapted to provide a procedural framework that is multideterministic and accessible to engineers who rely on the current state of practice. The mathematical formulation of the proposed approach is discussed, and a design example is provided in which the proposed framework is demonstrated.
