Moment‐resisting joints in high‐strength steel: areas for improvement in design standards

In Memoriam of Prof. Dr. Bernt Johansson European standard EN 1993 does not permit the design of joints made from steel with a yield stress > 460 MPa using the principles of semi‐continuous/partially restrained construction, and will remain forbidden in its current revision within the scope of the CEN/2014‐02 programme for the evolution of the structural Eurocodes. The findings of a comprehensive research programme on the non‐linear behaviour of moment‐resisting joints with components made from high‐strength steel grades (yield stresses of 690 and 960 MPa) carried out at Delft University of Technology are summarized in this paper and used to reappraise these restrictions.
