Abstract
Fire safety engineering is a critical aspect of building design, particularly as traditional approaches based on standardized conditions may not fully capture the dynamic nature of real-world fire scenarios. This research focuses on the impact of temperature-dependent material properties, specifically thermal conductivity, on fire conditions modelling, with an emphasis on rock wool panels used for HVAC duct protection. The study aims to enhance the accuracy of fire resistance assessments by incorporating temperature sensitivity into models and optimizing rock wool panel thickness under standardized fire conditions. Hypotheses suggest that considering temperature-dependent properties will reveal significant differences in thermal behaviours, and optimizing panel thickness can provide insights into performance-based design. The study introduces a simplified numerical model and emphasizes the importance of diverse fire scenarios in designing fire protection systems. While economic advantages can be gained through parameter adjustments, the study calls for more sophisticated models to further enhance results and explores a range of optimization possibilities for fire protection systems.Description
