High strength steels in steel construction
The new European unified technical design rules for steel structures in Eurocode 3 are applicable to steels S235 to S460. It is intended to extend these rules in a second step to steels S690 and other high strength steels to benefit from the weight saving and reduced fabrication costs of using thin plates. In this contribution some problems in preparing design rules for high strength steels are presented and solutions are given for steels S460 and also for S690 for some applications. These solutions are mainly based on the results of large scale tests for which the Eurocodes provide a standardised evaluation method to achieve sufficient reliability. Tests carried out for determining resistances of components with high strength steels have revealed that for some resistances high strength leads to over proportionate resistances as for column buckling or plate buckling. Resistances are under proportionate for fillet welds. Restrictions for the use of plastic design can be bypassed by appropriate rotation assessments for which capacity data are available. For reasons of sensitivities to flaws it seems that for steel grade higher than S640 a strain oriented design would be appropriate.
