A Performance-Based Framework For Structural Resilience To Blast-Induced Damage, Shalva Marjanishvili, Spencer Quiel, Brian Katz Jan 2014

A Performance-Based Framework For Structural Resilience To Blast-Induced Damage, Shalva Marjanishvili, Spencer Quiel, Brian Katz

International Institute for Infrastructure Resilience and Reconstruction (I3R2) Conference

This paper proposes a framework for establishing quantitative measures and mathematically reproducible definitions of structural resiliency as it pertains to a structure's ability to minimize the potential for undesirable response to low-probability-high-consequence events. The resiliency assessment and design process follow a logical progression of steps starting with the characterization of hazards and continuing through analysis simulations, damage modeling, and loss assessment by balancing functional relationships between design tradeoffs and associated consequences. The outcomes of each subprocess are articulated through a series of generalized variables: topology, geometry, damage, and hazard intensity measures. A rigorous probabilistic framework permits consistent characterization of the …
