Sažetak
This paper examines the impact of different modelling choices on the fire performance of RC columns using Eurocode 2 in a real-world case study. The methodology includes a comparative analysis of simplified and advanced numerical simulations, employing FDS for fire curves and ABAQUS for thermal and mechanical analyses. Results show how modelling assumptions affect load-bearing capacity and fire resistance. Conclusions emphasise balancing safety and efficiency, highlighting the importance of variable axial loads and multiple heat zones for accurate fire resistance assessment.
