A fire in a ham factory in San Daniele del Friuli caused serious damage to the prefabricated reinforced concrete
(r.c.) roof panels and smaller damages to beams, columns and walls. In this paper the data captured during
preliminary inspection of the building structure are described. To determine the residual strength of steel reinforcements
and concrete of r.c. structural elements, a test program with laboratory and in situ tests is presented.
The program includes test methods that are able to catch the variability of concrete degradation with
distance from the heated surface. Test results are presented and their acceptability in relation to Italian Code is
discussed. It is found that the amount of transversal and longitudinal reinforcements strongly influences the
deterioration of the concrete due to fire and, consequently, the strength of structural elements. On the basis of
tests results, a discussion on the advantages and limitations of the adopted test methods useful for the designers is
performed. To restore the load-bearing capacity of the structure, repairs of columns and beams in the first three
bays of the central frame are proposed together with the substitution of the roof over the receiving area.
