FIRE RESISTANCE, TUBE-CONCRETE STRUCTURES, MECHANICAL LOADS, TEMPERATURE MODES, CALCULATION METHOD The purpose of this work is to reveal the laws of the dependence of the fire resistance limit of circular concrete columns of circular cross section on their geometrical characteristics and the actual mechanical load under the influence of the standard temperature regime of a fire, as the basis for improving the simplified computational method for estimating it. The object of research is the processes of deformation, destruction with loss of fire resistance occurring in round-shaped pipe-concrete columns when exposed to the standard temperature of the fire. The subject of research is the laws of changes in the value of the fire resistance of pipe-concrete columns of circular cross section, depending on their heating temperature, geometric parameters, thermal characteristics of metal and concrete, parameters of fire-retardant systems and mechanical load when exposed to standard fire conditions. Traditional methods for the numerical study of the fire resistance of multilayer structures are based on the study of its loss of strength and integrity under standard fire conditions. These methods can be effectively used for a certain range of technical problems, since the mechanism of destruction of multilayer structures depends on temperature displacements and the stress-strain state of the structure in a real fire. Thus, the creation of an engineering method for calculating the fire resistance of multilayer building structures is an actual scientific and technical problem of the present.
