The article shows results of behavior research of reinforced concrete beam exposed to fire using standard “time-temperature” curve. Practice of fire resistance estimating for reinforced concrete beams based on experimental and calculation method was developed and tested on the basis of the study results. Block diagram of temperature determining algorithm for nodal points of the cross-section by interpolation of temperature values in measurement points of the cross-section was showed. The fire test of reinforced concrete beams was carried out and a temperature distribution in cross-section of beams was defined based on it by application of interpolation techniques developed. The sequence of procedures of the strength calculation method based on temperature measuring in the inner layers of reinforced concrete beams was demonstrated. Fire resistance of the reinforced concrete beams under question was evaluated based on the interpretation of the data obtained during the fire tests and using the proposed method of strength calculating.
