Probabilistic Performance Based Risk Assessment Considering the Interaction of Wind and Windborne Debris Hazard

This paper introduces a probabilistic Performance Based Hurricane Engineering (PBHE) framework for risk assessment based on the total probability theorem. This methodology disaggregates the risk assessment analysis into independent elementary components, namely hazard analysis, structural characterization, interaction analysis, structural analysis, damage analysis, and loss analysis. The proposed PBHE framework accounts for the multi-hazard nature of hurricanes. The procedure for the probabilistic risk assessment is illustrated through an application example consisting of a residential house subjected to the combined hazards of windborne debris and hurricane strong winds. © ASCE and ATC 2013.
