Considering Weld Eccentricity in RFEM 6

Is it possible to consider the eccentricity of unsymmetrical line welds for the stress analysis in RFEM 6?


Answer:

Yes, it is. The Special Options of the Line Welded Joint Configurations provide you with the option to activate the consideration of the weld eccentricity. This is not always necessary. For example, according to EN 1993‑1‑8 [1], Section 4.12, the weld eccentricity can be neglected if a hollow section is connected uniformly over the entire perimeter, or if the eccentricity leads to an increase of compressive stresses in the weld root.
