Bemessung von Tragwerken aus höherfesten Stählen bis S700 nach EN 1993-1-12

Design rules for structures made of high strength steels up to S700 according to EN 1993-1-12.

Due to the implementation of Eurocode 3 and EN 1090-2 design and execution of steel structures made of high strength steel of grades higher than S460 up to S700 are mostly regulated by standardization. EN 1993-1-12 contains supplementary rules for these steel grades, which have to be considered when applying other parts of Eurocode 3. Differences with regard to high strength steels, for example, result from lower plastic deformability. The possibility to design more slender structures increases the relevance of deformations and stability effects. Further differences are reflected in resistance and deformation capacity of bolted and welded connections. The following article describes special design rules for structures made of high strength steels and their joints and demonstrates their potential compared to conventional steel grades.
