Abstract
: This paper describes the calculation of the fi re resistance of reinforced concrete column that is exposed to fi re from two sides. Calculation of the temperatures has been made depending on whether the heat fl ow within the reinforced concrete column is one-dimensional or two-dimensional. The temperature of concrete and the temperature of reinforcement are calculated by the Hertz's method. The values of concrete strength and reinforcement, as well as the width of the damage zone of concrete during a certain period of exposure to fi re have been calculated. Resistance to the effects of fi re on reinforced concrete column has been calculated by the zone method. The time of the resistance of column to the effects of fi re has been determined according to the moment capacity of reinforced concrete column.
