Summarises the findings of a study carried out at Cranfield University during 1992-94 to evaluate the significance of yield ratio and changes in work hardening capacity in relation to structural performance. The reasons behind these changes in steel behaviour are identified and the impact on design approach and suitability of current code provisions is assessed.

New information is presented that supports the specification of higher strength steels and provides grounds for a re-appraisal and broadening of the scope of current codes and design rules, which would ensure their safe, efficient and cost effective use in future offshore construction. The study also identifies areas where further work is required in order to provide the necessary supporting information to carry out a revision of design codes.
