Fire-Resistant Structural Performance and Reinforcement Strategies in Petrochemical Facilities

This study evaluates the fire-resistant structural performance of column members in petrochemical plants and proposes reinforcement strategies. The pre-fire analysis examines current fireproofing methods and suggests improvements using advanced fire-resistant coatings. The post-fire analysis assesses residual strength and recommends appropriate structural reinforcement techniques. Thermal analysis indicates that hydrocarbon fires can raise column temperatures by 150-200 ℃ more than standard fire scenarios, emphasizing the need for preventive reinforcement. Post-fire structural analysis shows that residual strength may decline to below 59% as temperature increases, indicating a substantial loss of load-bearing capacity under extreme thermal conditions. These findings suggest that existing fire-resistance standards may be inadequate for petrochemical environments. Therefore, stricter evaluation methods and enhanced design criteria are necessary to ensure structural safety. This study supports the revision of fire-resistance guidelines for critical infrastructure in high-risk inductrial setting.
