Data-informed decision support framework for wind hazard mitigation
Speaker: Arthriya Subgranon, Daniel Solano, Thays Duarte, Imad Alhayik, Steven Klepac
Department of Civil and Coastal Engineering, University of Florida, Gainesville, FL
Urgent need to reduce losses in extreme wind events has prompted decision makers and engineers to develop risk mitigation strategies that aim to improve structural performance as well as the community resilience overall. This seminar will introduce a variety of research that has been going on at UF within the research group led by Dr. Arthriya Subgranon. Dr. Subgranon will introduce performance-based wind engineering (PBWE) frameworks which have been developed to rigorously predict the dynamic responses of wind excited systems and relate predicted engineering demands to performance metrics that are meaningful to decision-makers. The talk will also focus on the integration of structural optimization to create automatic algorithms that help explore the design space more efficiently. Daniel Solano is integrating carbon emissions as an objective to the construction of tall buildings, utilizing multicriteria optimization schemes and PBWE in the efforts to reduce the global greenhouse gases attributed to the building industry. The talk will also cover designing efficient code for this computationally expensive task. Thays Duarte is investigating the application of performance-based optimization design together with a life-cycle assessment to develop frameworks that can assist in the decision-making process to obtain more economical, reliable, and environmentally friendly wind-excited structures. Imad Alhayik is going to present the application of computational fluid dynamics (CFD) and how it could add a contribution to the Civil Engineering field. Steven Klepac is training machine learning models to predict structural damage at the community level. Economic and societal loss models will be incorporated into the forecasting framework to enable community decision-making under multi-factor uncertainty.
Dr. Subgranon is an assistant professor in the Department of Civil and Coastal Engineering at the University of Florida, where she received her BS degree (Summa Cum Laude). She earned a PhD degree in Civil Engineering from the University of Michigan. Steven Klepac and Thays Duarte are PhD students while Daniel Solano and Imad Alhayik are master’s students in her research group at UF. The research conducted in her group involves the general area of structural engineering with particular emphasis on reliability, performance-based design, structural optimization, probabilistic modeling and uncertainty propagation, and natural-hazard mitigation. The group aims to expand her efforts to areas that contribute to the resilience and sustainability of the built environment, such as life-cycle engineering, post-hazard recovery, and data-informed decision making.
