abstract = {<div data-language="eng" data-ev-field="abstract">Steel WF or I-shapes are usually fabricated by either hot-rolling or welding. Both manufacturing processes produce residual stresses that affect the stability behavior and resistance, namely at the member level (e.g., flexural or lateral torsional buckling). Yet, at the cross-sectional level, design provisions typically ignore the influence of residual stresses and propose identical sets of equations for hot-rolled and for welded sections. This paper numerically evidences that this should be improved and investigates how much more detrimental welded residual stresses patterns can be in comparison to hot-rolled ones, in various contexts. The results of detailed non-linear shell F.E. simulations on various geometries, slenderness, material grades and load cases are reported and analyzed, and recommendations for code improvements are proposed.<br/></div> © SSRC 2024.
