    Abstract. The calculation of structures reinforced with composite materials during normal operation is described in some detail in the current set of rules of normative document and a number of studies. The problem when designing such reinforcement is the selection of a flame retardant to ensure fire resistance. The flame retardant composition must have properties that will ensure a temperature in the composite material and adhesive composition of no more than 50 ... 60 °C. The thermally expanding coatings available on the market, as a rule, are able to ensure the fire resistance of the reinforcement system with composite materials for no more than 120 minutes. A longer time to ensure fire resistance in most cases is achieved by using heat-insulating materials. The calculation of the thickness of the insulating material in many cases is reduced to solving the problem of finding the temperature field in the cross section with a non-stationary heat flow. An engineering approach that makes it possible to choose the thickness of the heat insulating material is presented. This approach is based on the modification of the existing calculation method for calculation of the temperature field for reinforced concrete structures without the use of a computer. The calculation results are compared according to the developed engineering methodology with the exact solution obtained in the Abaqus PC.
