Interaction of Mechanical Systems with Structurally Significant Fire Events (UTI-UTC 44)

This research project explores the coupled interaction between mechanical systems—such as ventilation ducts, electrical conduits, and fire suppression infrastructure—and tunnel structures during significant fire events. Recognizing that these systems can influence and be affected by thermal and structural responses, the study develops advanced computational tools to simulate fire dynamics and their impact on structural components. Using Computational Fluid Dynamics (CFD) and Finite Element Analysis (FEA), the project models fire spread, heat transfer, and the degradation of mechanical systems, while also assessing how these systems alter the fire’s behavior and the tunnel’s performance. The goal is to inform the design and placement of resilient systems that maintain functionality and support tunnel integrity during emergencies. Outcomes include a beta version of a predictive fire assessment tool, validation through experimental and historical data, and recommendations for improving tunnel system safety and resilience under fire loading scenarios.
