Abstract:
Hot-rolled steel is a common material in modern high- rise and long-span structural systems. Despite its structural advantages, its rapid strength deterioration at elevated temperatures makes it vulnerable to fire events. This study aims to evaluate the effectiveness of passive fire-resistant systems in enhancing the fire endurance of hot-rolled steel elements. A series of tensile coupon tests were conducted on uncoated specimens subjected to temperatures ranging from ambient to 1200°C. Cooling was performed using both air and water quenching methods. The mechanical properties, including stress-strain behaviour, yield strength, ultimate strength, elastic modulus, and elongation, were analysed. Results indicate significant performance variations based on cooling method, offering critical insights for fire- resistant design in steel structures.
