Influence of wind load on fire resistance limits of steel structures of oil and gas industry facilities
https://doi.org/10.22227/0869-7493.2025.34.05.5-15
Abstract
Introduction. Accidents at oil and gas facilities occur every year. Current Russian regulations require testing to determine the fire resistance of structures under standard temperature-time curve and do not take into account the specific features of the production facility’s technological processes, its location, or the climatic parameters of the surrounding environment.
Aims and Purposes. Assess the impact of wind on the fire resistance limits of steel structures in oil and gas industry facilities. Determine the wind load for each facility. Based on previously created field models, develop fire calculation models that take wind effects into account.
Methods. The calculation was performed using FDS in Pyrosim software based on information models of objects developed in Revit software. Monin – Obukhov similarity theory was used to determine the wind impact on objects.
Results. Based on the simulation results, the areas of spread of the fire front were determined for each of the objects. It was shown that the increase in the radius of the fire’s zone of influence ranges from 4.5 to 8.6 m.
Conclusions. The results of the calculation, taking into account wind load, demonstrate a significant expansion of the fire’s area of influence. It can be concluded that ignoring wind load when determining the fire resistance limits of structures or developing a fire protection design is unacceptable, since wind significantly increases the area of the fire’s impact zone and, consequently, the volume of structures requiring fire protection.
