Abstract:
This workshop provides a comprehensive introduction to the application of street view imaging systems in natural hazard research and assessment. Participants will gain hands-on experience with state-of-the-art street view data collection techniques, post-processing methods, and machine learning tools for extracting valuable information from street-level imagery.
The workshop will cover:
This workshop is designed for engineers and scientists working in the natural hazards field who seek to incorporate advanced imaging and data analysis techniques into their research and assessment workflows. Participants will leave with a solid foundation for implementing these tools in their own work, enhancing their ability to identify, quantify, and mitigate potential hazards in urban and rural environments.
The RAPID Facility enables transformative research by equipping natural hazard and disaster researchers with essential resources to collect, process, and analyze perishable data from extreme events. These comprehensive open datasets enable the development and calibration of scientific natural hazard simulation models. Our work supports NSF-supported researchers, extreme event reconnaissance (EER) organizations, and federal agencies.

This session provides an overview of the BRAILS and R2D tools developed by SimCenter, highlighting their individual capabilities and how they can be integrated for comprehensive natural hazard loss assessments. BRAILS is a powerful computational engine designed to automatically generate detailed inventories of building and infrastructure elements. R2D is a desktop software application that integrates BRAILS and other tools/libraries for characterizing hazard events, and simulating damage and losses across large inventories of buildings and civil infrastructure. Recent developments have expanded R2D's capabilities to evaluate the post-disaster performance of transportation and lifeline infrastructure systems, as well as to simulate community recovery. Through practical examples, this session will showcase how BRAILS' automated inventory generation can seamlessly integrate with R2D's library of methods to assess the regional and system-wide impacts of natural hazard events.
This session introduces SimCenter’s quoFEM application, a tool designed to enable Uncertainty Quantification (UQ) analyses for computational simulation models. Through its graphical interface, quoFEM guides users through four steps in setting up UQ analyses: selecting a UQ algorithm and options, specifying model scripts, defining input probability distributions, and identifying model outputs.
With quoFEM, users can propagate uncertainties in both model parameters and the models themselves, evaluating their impact on quantities of interest. If data is available, quoFEM also supports updating these uncertainty distributions. To handle the computational demands of UQ analyses, quoFEM enables seamless job execution on high-performance computing resources through DesignSafe, accessible directly from the user’s local computer.
This session will showcase a variety of UQ analysis options within quoFEM, including global sensitivity analysis, surrogate modeling, multi-fidelity Monte Carlo simulation, and surrogate-aided Bayesian calibration for computationally expensive models through examples to demonstrate opportunities for adapting uncertainty quantification into active research and proposal ideas.

This session introduces the advanced computational fluid dynamics (CFD) capabilities implemented within SimCenter’s WE-UQ tool to enable computational wind engineering studies. These features include streamlined CFD workflows to assess the wind-induced loads and responses on structures. The session begins by discussing the key steps needed for a successful CFD-based wind load simulation inlight of the recent advances in computational wind engineering. Next, the implemented CFD-based workflow is described in detail emphasizing the newly incorporated features that allow users to create or import building geometries, generate automated unstructured mesh, define boundary conditions, run simulations on HPC resources provided by DesignSafe, and post-process results. Finally, the developed workflow is demonstrated through two examples: the first illustrates creating a digital twin of an existing wind tunnel testing facility and validating it against experimental data; the second example applies the workflow to evaluate cladding and overall loads on a high-rise building.
This session will introduce the high-performance computing (HPC) resources available through DesignSafe, including multi-node clusters, GPU-enabled systems, and research storage capabilities, along with the streamlined process to gain access. Demonstrations will showcase research workflows using software such as OpenSees, ADCIRC, ML tools, and OpenFoam. Participants will learn multiple approaches to job submission, including through the web portal interface, interactive Jupyter notebooks, and command line tools.
