Abstract:The USDOT's top concerns are deterioration of transportation infrastructure and how it affects overall structural performance over time. Transportation infrastructures become more vulnerable to various natural hazards and calamities owing to the structural degradation caused by physical or chemical factors. Accurate assessment of structural performance under extreme events and potential performance degradation due to any damages reported from routine infrastructure inspection is required to increase the resilience of such deteriorating transportation systems. Additionally, information about how the detected defects would impact overall infrastructure performance should be easily accessible for decision-makers and stakeholders to maintain and operate the transportation system properly. To readily check the location of significant damages, their effects on infrastructure hazard vulnerability and the projected economic and life losses from an expected hazard, an enhanced and interactive hazard risk management framework for transportation infrastructures is urgently needed. The objective of this project is to provide an integrated hazard vulnerability assessment and mitigation framework for transportation infrastructures with mixed reality (MR) and progressive vulnerability evaluation. Engineers will be able to monitor damage and degradation propagation over time, reduce hazard risk, predict the remaining lifetime of transportation infrastructure, and optimize maintenance time and cost with the help of the suggested framework. The analysis results from complex structural performance assessment will be more easily accessible and more understandable for decision-makers with the aid of MR technology.
