EN-1993 covers steel grades up to S460, and with small adjustments, up to S690.
In “RuOSte” the existing rules and requirements will be examined with regard to more economic and feasible design rules, covering steel grades up to S960.
The main questions regarding ductility, strength of welded joints, tubular joints and stability will be addressed. In several case studies, impact of recommendations developed in the project for designing structures of HSS will be evaluated.
