摘要：
FIELD: fire safety.SUBSTANCE: invention relates to the fire safety of buildings, in particular the fire resistance of reinforced concrete elements of building structures, and concerns the investigation and analysis of the quality of stretched reinforcement by means of thermal means when the load is exposed to a joint and the high temperature of a standard fire. Method for detecting the resistance to stretching of the reinforced concrete element in a fire condition includes conducting a full-scale inspection of a reinforced concrete element, measuring its geometric dimensions, identification of the reinforcement scheme, the determination of the type of concrete and its thermal characteristics, the size of the protective layer of concrete and the depth of occurrence of the stretched reinforcement, the determination of the type and class of the reinforcement by strength, its standard resistance and the value of the critical heating temperature, the coefficient of change in the standard resistance of heated reinf
