Task Description: OpenSRA is a desktop application that owners and regulators can use to evaluate the seismic performance of natural gas infrastructure and the potential effectiveness of system upgrades. The tool provides a user-friendly interface to view results, including risk maps, population overlays, and exposure estimates. OpenSRA2 will incorporate data from remote sensing and embedded sensing technologies with the OpenSRA models so that the measured data interact at every stage of performance assessment and the models are updated appropriately, resulting in improved model outputs for future performance assessments.
The SimCenter’s open-source application Regional Resilience Determination Tool (R2D) is a graphical user interface that facilitates the high-resolution assessment of hazard risk on the built environment at a regional scale. This project’s remote and embedded sensing data, along with their uncertainty, will be used with Bayesian calibration to update predictions of regional risk.
A digital twin model of field demonstration sites for the remote sensing and embedded sensing applications will be developed in order to leverage information and tools available from the research team. The digital twin model will include 3-D models of the site, historical landslides, creeping landslides, and subsurface information. The monitoring data will feed into the OpenSRA and into SimCenter’s application R2D to demonstrate a complete system approach, including sensors, field data collection, data management and analysis, and risk assessment.-
