Stresses for Weld Seam Design

In RF-STEEL Surfaces, it is possible to display the stresses relevant for the design of welds, for example, according to EN 1993‑1‑8, Figure 4.5. When evaluating the stress components, the local xyz-axis system of the surfaces must be considered.

The example shows the weld connection of a frame joint. The surface y-axis of a truss flange is parallel to the weld axis. For the superposition of stresses according to EN 1993‑1‑8, Eq. (4.1) the following stresses are considered:

  • σ⊥ (normal stress perpendicular to weld axis): σx,m
  • σ‖ (normal stress parallel to weld axis, insignificant): σy,m
  • τ⊥ (shear stress perpendicular to weld axis): τxz
  • τ‖ (shear stress parallel to weld axis): σxy,m

The stress components can be set in the Results Navigator and displayed in the FE mesh points.
