“…For example, steel structures can be treated with bulging flame retardants, or an additional layer of heat-resistant material with a low coefficient of thermal conductivity (for example, mineral wool slabs) can be applied to the surface. There are also many known ways to increase reliability, including the fire resistance of wooden and other structures by Mróz et al (2016) [20], Buchanan (2015) [21], Gravit et al (2023) [22], and Golikov et al (2016) [23]. There are currently no certified flame-retardant swelling compounds or other rational methods for cast-iron structures.…”

When reconstructing cultural heritage sites, significant changes to the original design planning are not allowed. More rational methods are needed to increase the fire resistance of historical buildings, which will ensure their fire safety and preserve their architectural value. Nowadays, most heritage sites do not meet the safety requirements of modern buildings. The purpose of the study is to develop a methodology for increasing the fire resistance of cast iron structures. The key tasks are increasing the fire resistance of buildings during reconstruction and ensuring their fire safety during operation. The tasks have been achieved by developing a new methodology for increasing the fire resistance of cast iron. It includes an integrated approach to assessing the risk of a fire, a predictive model for the occurrence of fire danger, as well as various scenarios for the fire development caused by cast iron heating. The results’ analysis has allowed us to determine the fire resistance limits of cast iron structures. The scientific novelty lies in the study of the fire resistance of cast iron structures using a three-dimensional mathematical model. The resulting values have been obtained via differential equations of the laws of mass conservation, momentum, gaseous energy, and the optical density of smoke.

“…All structural calculations were performed in SP QuickField 7.0 using the finite element method based on a two-dimensional finite element model [54]. SP QuickField 7.0 (in another version, SP ELCUT) was repeatedly used by the authors to solve thermophysical problems with the purpose of verifying the experimental data [20,55,56].…”

Fire protection is required to protect metal structures of oil and gas facilities from fires. Such fire protection should provide high fire resistance limits: 60, 90, 120 and more minutes. Specialists of LLC “RPC PROMIZOL ” developed a multilayer, removable type of fire protection made of superfine basalt fibre and ceramic materials for operation in Arctic conditions. Five experimental studies were carried out in standard and hydrocarbon fire regimes. The fire protection effectiveness of the products for I20 beams without load was obtained: a 50 mm thick coating provided 130 min of a standard fire regime; a 15 mm thick coating provided 60 min. The 15 mm thick coating provided 30 min of a hydrocarbon fire regime and the 50 mm thick coating provided 93 min of a hydrocarbon fire regime. The I40 beam under a load of 19.9 tf showed an R243 for the standard fire regime. The coefficients of effective thermal conductivity and specific heat capacity of fire-retardant compositions were determined by solving the inverse heat conduction problem. The problem was solved by modelling using the QuickField 7.0 software package, which implements FEM. Modelling showed that for obtaining the fire resistance limit R120 under the standard fire regime for the sample steel structure from an I40 beam, it is enough to apply fire protection with a thickness of 25 mm instead of 50 mm, which agrees with the experimental data. For the hydrocarbon regime, it is predicted that R120 can be obtained at a thickness of 45 mm instead of 50 mm.

The review of scientific and technical literature on the problem of ensuring fire safety of public and industrial buildings by dividing rooms into fire compartments using transformable fire barriers (TFB), as well as by protecting openings with transformable fire fillings is presented. The general classification of TFB is presented, the requirements for TFB are described, the use cases of various types of TFB and their design features are considered. Engineering solutions for transformable fire shelters, as well as mobile fire barriers, are presented. It has been established that the fire resistance limit of TFB is higher when used in combination with water irrigation, but the disadvantage of the system is the high consumption of coolant (from 0.12 liters/s of water per 1 linear meter of opening width), which, in addition to material costs, also has a destructive effect on finishing materials and building structures. A possible way to solve these problems is to use various fillers in the working cloth that emit inert or extinguishing gases, but this method needs additional verification in the form of modeling and physical experiments.
