Effects of state‐of‐the‐art residual stress models on the member and local stability behaviour

Residual stresses have considerable effect on both the local and member stability behaviour of steel structures. Previous studies shown that structural depends distribution amplitude residual stresses. The stress is affected by cross-section geometry, grade manufacturing process, e.g. flame cutting welding procedure. A realistic consideration necessary for an efficient safe design This article presents experimental numerical study influence members, i.e. columns beams considering a variety cross-sectional slenderness, plastic, compact slender cross-sections are taken into account. novel model welded I-shaped sections was developed evaluated using test data. takes account main influencing parameters, as well process with thermal cuts or non-thermal plates. then used to investigate in terms simulation study. result allows propose improvement buckling curve selection high strength beams.
