Evaluating the Importance of Interdependent Civil Infrastructure System Components for Disaster Resilience of Community Housing

Housing disaster resilience is crucial for community disaster resilience as it provides two essential functions: shelter from the elements and functional housing. We present a methodology to quantify community housing disaster resilience considering the unmet post-disaster community demand for both shelter and functional housing. Total Sobol' indices are used to evaluate the importance of the vulnerability and recoverability of individual components of community infrastructure systems and building stock units for community housing disaster resilience, while requiring no prior knowledge of these component properties. We illustrate the application of the proposed importance analysis on a virtual community considering the functionality of the electric power supply, water supply and communication infrastructure systems, and a number of building stock units.
