2. The choice of the steel grade
In general, the choice of the steel grade is ruled in Eurocode EN 1993-1-1 (2005). Several
requirements are specified:
Choice according to the mechanical material properties
Nominal values of material properties are defined as characteristic values in design cal-
culations.
Ductility requirements
For steels, a minimum ductility is required.
Toughness properties
