Major Outputs 

The aim of the project is the development of new, direct design rules regarding strength and stability checks based on the “Overall Interaction Concept”. Addressing both usual steel grades as well as tomorrow’s high strength steels, this project allows for more economic, innovative, “thin-walled” hollow section members. Simpler and faster design procedures were developed, and both numerical tools and the latest statistical production data were made available to structural engineers.

These goals were tackled by means of extensive numerical, analytical and experimental programs, with the close collaboration of key European hollow section manufactures from different EU countries.
