The paper presents field experiments and analytical description results of physical and technical parameters of bending reinforced concrete structures and their fire resistance. The results take into account the burial depth of working reinforcement, the thermo-diffusion value of protective layer concrete, the degree of reinforcement fire resistance, the nominal diameter of working reinforcement. The degree of reinforcement fire resistance is characterized by the thickness of the protective layer of concrete that changes its size and thermal characteristics in conditions of high temperatures, corrected for the conditions of the center of gravity in the reinforcement cross-section heating up. The study reveals a mathematical description of the indicators, which take into account the value of concrete thermo-diffusion reduced coefficient, intensity of force tension in working reinforcement and the size of its diameter. Analytical functions are derived for these indicators. This research results can be used for making computer algorithms and programs to calculate design fire resistance of bending reinforced concrete constructions of buildings and constructions.
