When a building with a reinforced concrete structure catches fire, the members of that structure are affected to a varying degree depending upon the duration and maximum temperatures of the fire. The present article describes a nondestructive method that makes it possible to calculate the average calcination depth of the structural members by means of measuring the transmission times of ultrasonic beams through the affected element. The article ends proposing suitable considerations and indications for elaborating an electronic calculation programme capable of handling the great quantity of data proceeding from a fire of average range.
