Steel Properties And Requirements for Constructional Steelwork (SPARCS)

Owing to recent technological advances in the steel industry, structural steels with modified properties can nowadays be produced and adapted to the specific requirements of the customer. These include strength, ductility and manufacturing properties, which are of particular importance for structural steel construction.

The project SPARCS (Steel Properties And Requirements for Constructional Steelwork) sets out to scientifically investigate the relationship between the heterogeneous technological properties of manufactured steel grades and the requirements for steel structures from different building typologies and under different regulatory and geographical boundary conditions. In particular, it is to be determined - for various representative steel grades - how the distinctive differences in the yield strength ratios, the hardening behaviour after exceeding the yield strength, the impact toughness as well as the cyclic behaviour under elastic and elasto-plastic shear and longitudinal stress can be exploited in a targeted manner in the context of the checks in structural steel construction. This should facilitate the construction of particularly resilient, safe and economical steel structures. Additional attention is to be paid to the connection between production monitoring and the statistically applicable design values of the steel properties for the verification in steel construction.
