The draft second generation Eurocodes have started to appear in the last couple of years. Among these, the Eurocode 1 Part 1-4 is dealing with the design of structures to wind action. In view of the opportunity of updating National Annexes (NAs), in this paper the attempt is made at calibrating wind load factors for Italy, also investigating the reliability of the current Italian extreme wind map. Overall, it is shown that load factor currently adopted by the Eurocodes and by the Italian NAs needs to be increased. On the other hand, the Italian extreme wind map should be revised to reduce the gap in terms of reliability level.

Abstract
The draft second generation Eurocodes have started to appear in the last couple of years. Among these, the Eurocode 1 Part 1-4 is dealing with the design of structures to wind action. In view of the opportunity of updating National Annexes (NAs), in this paper the attempt is made at calibrating wind load factors for Italy, also investigating the reliability of the current Italian extreme wind map. Overall, it is shown that load factor currently adopted by the Eurocodes and by the Italian NAs needs to be increased. On the other hand, the Italian extreme wind map should be revised to reduce the gap in terms of reliability level.File in questo prodotto:
