In the context of contemporary urban development, fire safety in public structures, particularly high-occupancy buildings, remains a paramount concern. The fire resistance of reinforced concrete (RC) frame structures, the primary load-bearing components, plays a pivotal role in ensuring life safety and mitigating property damage in the event of a fire. This research focuses on the application of advanced numerical simulation techniques, specifically utilizing ANSYS APDL software, to evaluate the fire resistance of RC frame structures in airport terminals conforming to EUROCODE standards. A detailed numerical model is constructed based on geometrical parameters, material properties, and realistic fire scenarios, enabling a thorough analysis of temperature distribution, stress, and deformation behavior of the structures under elevated temperatures. The findings not only validate the efficacy of ANSYS APDL in fire resistance assessment but also provide critical insights into the structural behavior of RC under fire conditions. Consequently, the research proposes optimized design solutions and engineering measures to enhance fire resistance, thereby ensuring the safety and operational continuity of airport terminals.
