The fire resistant ceiling construction in a hydrocarbon fire

Fire protection of building structures under the hydrocarbon fire is becoming more relevant, especially in the design and construction of oil and gas and chemical complex facilities, including offshore fixed platforms, liquefied natural gas production and storage facilities and other objects of the fuel and energy complex. The development dynamics of such a fire requires a different approach to testing the structures in order to determine the fire resistance limit. The fire resistance tests of a steel horizontal structure with a fire resistance suspended ceiling of PROMATECT-T plates were carried out under the condition of creating a hydrocarbon temperature combustion regime. A detailed description of the tested ceiling design is given. It is shown that at the time of the end of the fire action, the limit state due to the loss of load capacity (R) and loss of integrity (E) was not recorded when the test reached 120 minutes.
