Implementation of SEMI-COMP+ Design of semi-compact sections Original research title: “Plastic member capacity of semi-compact steel sections - a more economic design” funded by the Research Fund for Coal & Steel fully compatible with Euro. Code 3 (already in pr. EN 1993 -1 -1: 2015)

Implementation of SEMI-COMP+ Corrections to EN 1993 -1 -1: Moment resistance in Class 3 Section classification Benefits: more economic mechanically more logical simple to use conforms to existing rules in EC 3 (part 1 -3/1 -5) and international codes

Implementation of SEMI-COMP+ 1 st important consequence: Limited plastic moment resistance of Class 3 sections Only for symmetrical I-, H-, and box sections EN 1993 -1 -1 SEMI-COMP+
