Abstract :
[en] The objective of the paper is to assess the accuracy of current Direct Strength Method (DSM) equations applied to steel structural welded H shapes in axial compression. Commercialised hot-rolled H sections covering IPE, HE, HD, HL, HP, W and UB profiles and made of three grades (235MPa, 355MPa and 460MPa) were treated in (Li & Rossi 2012). This analysis focuses on welded sections made of the same three grades, including sections characterized by local buckling with a significant post-buckling reserve. The finite element model is described. Then, the results of a parametric analysis using the finite element model are re-ported. The codified resistances are also compared to the numerical results. For each cross-section, the recently developed analytical expressions provided in (Seif & Schafer 2010) for hot-rolled profiles are used to cal-culate the elastic cross-section local buckling stress. A comparison with CUFSM results is also reported. Then, the possibility to use the concept of DSM for the design of structural welded steel shapes is discussed.
