Interaction diagrams between axial load N and bending moment M for columns submitted to buckling : Improvement of methods proposed in standards and codes
Project ID: 7210-SA/510Funded under: ECSC-STEELRES 7C
The purpose of this research was to check by means of buckling tests the behaviour of HD columns submitted to eccentric loading, and to compare the results with the values calculated according to Eurocode 3 and other national standards. Numerical simulations of different profiles with Finelg software have been compared to design rules issued from Eurocode 3. These comparisons led to the testing programme of 13 thick flange HD columns in FeE 355 steel grade with flange thicknesses from 52 to 125 mm. The test results were compared with Eurocode 3 design and formulae (1984 and 1990 versions), with Swiss formulae (Sia 161-1990 version) and with Finelg simulations which are closer to the reality. The comparisons were carried out for the whole N-M interaction curves including different phenomena: buckling, resistance of cross-sections, lateral-torsional buckling and bending.
