Experimental investigation into high strength Q690 steel welded H-sections under combined compression and bending

It should be noted that the measured failure loads were compared with the predicted resistances of these H-sections based on their measured geometrical and material properties according to various design rules given in EN1993-1-1, ANSI/AISC 360-16 and GB 50017-2003 respectively. Among all these three sets of design rules, EN1993-1-1 is shown to be effective and efficient in predicting resistances for high strength Q690 steel welded H-sections under combined compression and bending with properly selected parameters. Hence, EN1993-1-1 should be readily adopted by design and construction engineers in designing these Q690 steel welded H-sections under combined compression and bending.
