Damage Assessment in Actual Fire Situations by Means of Non Destructive Techniques and Concrete Tests

In the paper the problem of the damage assessment in post real fire situations is discussed once more at the light of some integrated non destructive testing procedures. The illustration of the method is developed with reference to a real fire accident where extensive laboratory and site analyses were worked out. The analysis of the compartment and the concrete investigation results allow to define the damage field in the structural elements and to design a sensible strengthening intervention leading finally to a safety margin not less than the original one.
