Despite modern seismic standards, like Eurocode 8, admit ductile design of steel and composite structures, current European production standards don't provide adequate limitations on steel mechanical properties limiting free application of such approach. Additional safety factors and design checks, aiming to guarantee optimal plastic hinges' location, must be foreseen, reducing practical applicability and possible advantages of seismic ductile design. The proposal aims at the definition of harmonised production and structural recommendations specifically for seismic areas, allowing design of ductile structures without any supplementary assessments on materials. Competitiveness, cheapness and safety of steel solutions in earthquake-prone areas will be highly increased.
