Abstract

This paper proposes a framework to evaluate hurricane resilience of residential communities. Building resilience often refers to community resilience instead of individual resilience. Few efforts have been made to relate individual resilience to community resilience in a quantitative manner subjected to hurricane events. The proposed framework includes disaggregating hurricane community resilience to the individual level and quantifying the resilience for individual residential buildings. The framework not only consists of hurricane damage assessment including hurricane fragility analysis, reliability analysis, and loss analysis, but also analysis of recovery time, which makes the assessment framework more comprehensive and accurate. Sources of uncertainties in the framework include (1) structural modeling uncertainty (e.g., changes in roof panel resistance due to effects of corrosion on metal fasteners), (2) load uncertainty (e.g., hurricane wind characteristics), (3) uncertainty in direct and indirect loss estimation, and (4) recovery time modeling uncertainty. It is found that a community could meet certain community resilience goals as long as the individual buildings in the community could meet the individual building resilience goals.
