“…Numerical simulations are used to evaluate the methodology, predict the behavior of building structures, obtain temperature distributions, stress and strain fields [36][37][38][39]. Generally, the numerical model will first be validated with experimental data and then analyzed to better understand the performance of the structure under both mechanical and fire conditions.…”

“…In [38], a simulation of heating of offshore stationary platform structures in SP ELCUT is given, which showed good correlation with the experimental data; the consumption of mineral slabs for the bulkhead structure is predicted and the parameters of thermal conductivity and the heat capacity of the applied fire protection in the temperature range from 0 to 1000 • C are specified. In [39], the results of large-scale fire tests of lightweight thin-walled steel structures for fire protection efficiency in the SP ELCUT are presented. As a result, temperature-time curves of metal structures in the standard fire regime were obtained, which showed a good correlation between the simulation and the experimental data.…”

The problems of the fire safety of oil and gas facilities are particularly relevant due to the increasing complexity of technological processes and production. Experimental studies of steel structures with three different types of plasters are presented to determine the time taken to reach the critical temperature and loss of bearing capacity (R) of the sample, as a result of reaching a rate of deformation growth of more than 10 mm/min and the appearance of the ultimate vertical deformation. The simulation of the heating of steel structures showed a good correlation with the results of the experiment. The consumption of the plaster composition for the steel column was predicted, which allowed a 38% reduction in the consumption of fireproofing. It was found that to obtain the required fire resistance limit, it is necessary to consider the fire regime and apply plaster compositions with a thickness of 30–35 mm, depending on their thermal characteristics. The dependence of thermal conductivity and temperature on density is obtained, showing that the use of plaster compositions with a density of 200 to 600 kg/m3 is optimal to ensure a higher fire resistance limit. It is shown that the values of thermal conductivity of plaster compositions at 1000 °C are higher by 8–10% if the structure is exposed to a hydrocarbon fire regime. It is shown that the values of the heat capacity of plaster compositions at 1000 °C are higher by 10–15% if the structure is exposed to a standard fire regime.

“…In general, it is assumed that the fireproofing composition is applied layer by layer and evenly over the entire surface of the protected structure with an intermediate drying procedure (lasting at least 4 h at ambient temperature +20 °C), conducted before the application of each additional (starting from the second) layer; if the design thickness of the fireproofing coating is 6 mm or more, on the treated surface of all external corners (ribs) of the structure, a reinforcing glass mesh is laid over the uncured layer of the fireproofing composition (Figure 5) [32]. Numerical simulation is used to predict the fire behavior of building structures and to obtain temperature distributions [33][34][35][36]. For the simulation of the thermophysical processes of steel structures, the authors used the software package (SP) QuickField 6.6 [37]; the possibility of the numerical simulation of the fire resistance of building structures has been repeatedly confirmed by the authors of scientific papers.…”

Different systems of fire protection coatings are used to protect the metal structures of stories and trestles at oil and gas facilities from low (when filling cryogenic liquids) and high temperatures (in case of the possible development of a hydrocarbon fire regime). This paper presents the results of experiments of fireproof coatings on an epoxy binder after the simulation of a liquefied hydrocarbons spill and subsequent development of a hydrocarbon fire regime at the object of protection and exposure of structures to a standard fire regime. According to the experimental results, the temperatures on the samples at the end of the cryogenic exposure were determined and the time from the beginning of the thermal exposure to the limit state of the samples at a hydrocarbon and standard temperature fire regime was determined. As a result, temperature–time curves in the hydrocarbon and standard fire regimes were obtained, showing good convergence with the simulation results. The solution of the inverse task of heat conduction using finite element modeling made it possible to determine the thermophysical properties of the formed foam coke at the end of the fire tests of steel structures with intumescent coatings. It was determined that an average of 12 mm of intumescent coating thickness is required to achieve a fire protection efficiency of 120 min and for the expected impact of the hydrocarbon fire regime, the coating consumption should be increased by 1.5–2 times compared to the coating consumption for the standard regime.

Glass is widely used for the manufacture of the facades and interior glazing of buildings. Glass structures are subject to high fire safety requirements. Two methods are employed in this work: experimental studies of small-sized and large-sized samples and simulations of heating glass structures. The results showed that large-sized samples of monolithic tempered glass, with dimensions of 4250 × 2000 × 8 mm and 2000 × 3000 × 8, that were inserted in a steel frame, if properly installed, provided fire resistance limits of E30/E45 and E60, respectively, for loss of integrity, which proves the influence of the dimensions of the glass panel on the fire resistance of the facade structure. The small-sized samples of monolithic tempered glass with dimensions of 1000 × 700 × 8 mm provided a fire resistance limit of E60 for loss of integrity. A large-sized sample of monolithic tempered glass measuring 4250 × 2000 × 8 mm and inserted into an aluminum frame provided a fire resistance limit of E60, proving the effect of the frame on the fire resistance of the structure. According to the results of several simulations, a conclusion was formed about the possibility of predicting the fire resistance limits of tempered glass based on its thickness and dimensions. During operations, these structures will be able to prevent the spread of fire and combustion products for the required time after the loss of integrity. The results of the study allow for the estimation of the influence of the scale factor on the falling of the glass from the frame in a fire (loss of integrity).
