New interaction formulae for beam-columns in Eurocode 3: The French-Belgian approach

New interaction formulae for beam-columns in Eurocode 3: The French-Belgian approach. Boissonnade, N., Jaspart, J., Muzeau, J., & Villette, M. Journal of Constructional Steel Research, 60(3-5):421 - 431, 2004. Lateral-torsional buckling;

Paper abstract bibtex

This paper presents one of the two new proposals for beam-column interaction formulae, which will be made available in the forthcoming EN version of Eurocode 3. It is based on second-order in-plane elasticity, and has been derived in order to exhibit an understandable physical background, as well as accuracy and consistency with the other resistance and stability formulae of the code. The formulae ensure all the required continuities: between the cross-section classes, from plasticity to elasticity when slenderness and axial force are increasing, and continuity between all the individual stability member checks and cross-section verifications. The paper shows how the basic format may be extended to cover a wider range of cases, i.e. spatial elastic-plastic behaviour with possible lateral-torsional buckling. Through an extensive comparison with the results of FEM numerical simulations of about 150 000 beam-columns, the proposal is found to be safe and accurate. © 2003 Elsevier Ltd. All rights reserved.
