Starting from the description of an important realization among the Italian orthotropic deck bridges, the Verrand viaduct, the discussion deals with a particular situation that has been resolved by the employment of High Strength Steel. The launching execution of the viaduct, in fact, required for the particular planimetric and altimetric plans of the area interested by the highway, the use of special equipments and large employment of high yield limit steels S690. The solution used was the best compromise between the actual technical state of art in such a steel structure and the final result, taking obviously in account the technical and economical aspects. These aspects are clearly discussed in the text to focus when and where it was the best compromise and there are given some indications to know why chose a high or super high strength steel instead of a standard steel type.

Abstract
Starting from the description of an important realization among the Italian orthotropic deck bridges, the Verrand viaduct, the discussion deals with a particular situation that has been resolved by the employment of High Strength Steel. The launching execution of the viaduct, in fact, required for the particular planimetric and altimetric plans of the area interested by the highway, the use of special equipments and large employment of high yield limit steels S690. The solution used was the best compromise between the actual technical state of art in such a steel structure and the final result, taking obviously in account the technical and economical aspects. These aspects are clearly discussed in the text to focus when and where it was the best compromise and there are given some indications to know why chose a high or super high strength steel instead of a standard steel type.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
